Nonionic surfactant
Oleamide is a non-ionic surfactant and is white powder-like or flake-like at room temperature. It is nontoxic, insoluble in water and soluble in hot ethanol, ether other organic solvents. It is obtained by refinement of vegetable oil. It has special internal and external lubrication effect and is relative stable to heat, oxygen, and ultraviolet. It has various kinds of properties including anti-adhesive, slipping, leveling, waterproof, moisture-proof, anti-settling, anti-fouling, anti-static electricity and dispersion. Its effects of anti-sticking, anti-static and dispersion are very strong with no hydroscopic property. It is mainly used for high-pressure polyethylene (LDPE) film and composite film, multi-layer co-extruded film, gas-bag, super-thin film, and the slipping agent, anti-block and anti-static agent for polyvinyl chloride (PVC) calendaring film, polypropylene (PP) and curtain-coating polypropylene (CPP); it can also be used as the slipping agent and release agent of resins such as ethylene-vinyl acetate copolymer (EVA), poly-formaldehyde (POM), polycarbonate (PC), polyethylene terephthalate (PET) and polyamide (PA); it can also be used as the slipping agent and antistatic agent of PU surface treatment agent and fiber masterbatch; caking inhibiter, flatting agent, slipping brightening agent of plastic table printing (compound) inks and thermoplastic PE powder; the lubricant and dispersant of pigments, colorants and masterbatch; a indispensable excellent aids for functional opening, slipping masterbatch: it can also be used as metal protecting agent and the lubricants of polyolefin material.
Erucamide
Erucamide is a higher fatty acid amide and is an important derivative of erucic acid and is refined from vegetable oils. It is as waxy solid with no smell and is insoluble in water. It has certain solubility in organic solvents such as ketones, esters, alcohols, ether and benzene. Since the molecular structure contains long chain and unsaturated C22 chain polar amide group, it has excellent surface polarity effect with high melting point and good thermal stability. It can be as substitutes of other similar additive for being widely applied to other plastic, rubber, printing, machinery and other industries. As the processing aid for polyethylene and polypropylene plastics, it can not only make the products be not bonded and increase lubricity, but also can reinforce the thermoplastic and heat resistance of plastics and the product is also non-toxic. Foreign country has allowed it for being applied to foreign food packaging materials. Add the erucic acid amide into the rubber can increase the gloss of the rubber products, tensile strength and elongation rate and enhance the vulcanization accelerator and abrasion resistance with particularly efficacy in preventing the effect of the sun cracks. Adding it to the ink can increase the adhesion, scratch resistance, offset resistance and dye solubility. In addition, erucic acid amide can also be used as the surface lacquer of the calendared paper, protective films of metal and the foam stabilizer of detergent.

Slippery agent
At present time, common domestic varieties include amides (oleamide and erucamide), soaps (calcium stearate) and organic silicon (silicone). Organic silicon is liquid-like and is expensive as well as being inconvenient for adding usage. There is no domestic professional manufacturer and is difficult for application. Soap products, although is cheap, but has an unsatisfactory effect. It also demands a large adding amount and generally can’t be used in moderate-grade or high-grade products. The slippery agent, oleamide and erucamide has many advantages such as affordable price and significant effect, extremely small addition amount (0.05% to 0.3%), no toxicity (certified by the FDA), wide application range and broad application prospect.
Addition of 0.05%~0.3% oleamide to the low-density polyethylene film can not only improve the antistatic property and lubricating properties, but also improve the anti-moisture performance and can significantly reduce the coefficient of friction and adhesion resistance, significantly increase the efficacy of the membrane blowing (extrusion molding) and can effectively prevent the caking between the film and the agglomeration between the pellets. It may also increase the smoothness of the film surface and prevent the dust accumulation in the surface of the product, leading to very smooth plastic products.
In the polyolefin cable material and wholly plastic communication cable material, addition of oleamide (0.05%) can reduce the friction factor from 0.7 to 0.16 while changing its coloring as well as carbon black dispersion and achieve high-speed extrusion of cable aggregate material and improve the smoothness of the inner wall in the cable jacket pipe.
Adding 2-5 oleamide to the polyamide plastic ink can improve the printing performance and lubricity of ink, enhance the water resistance and scratch resistance and anti-offset characteristic (the fouling caused due to that the ink hasn’t become dry yet) and abrasion resistance. In addition, it can also improve the malleability and adhesiveness of the ink on the printed surface, so that the imprinting is clear and has bright color.

In recent decades, gels have been widely considered for various medicinal purposes and, in particular, wound healing applications. In this regard, amides of oleic acids and 9, 10-dihydroxyoctadecanoic acid are synthesized and characterized with the help of modern analytical tools. Among the mentioned amide frameworks, N-(2-aminoethyl)-oleamide exhibits high order of gelation not only with different organic solvents such as n-hexane and DMSO but also with different edible oils such as sesame oil, mustard oil, coconut oil and citriodora oil. Here, we briefly discuss the optimization of gelation conditions for the synthesized amides as organo-gelator, in addition to that the minimum gelation concentration and gelation temperature have also been studied.
Aerobic oxidation of primary amines to amides catalyzed by an annulated mesoionic carbene (MIC) stabilized Ru complex
Yadav, Suman,Reshi, Noor U Din,Pal, Saikat,Bera, Jitendra K.
, p. 7018 - 7028 (2021/11/17)
Catalytic aerobic oxidation of primary amines to the amides, using the precatalyst [Ru(COD)(L1)Br2] (1) bearing an annulated π-conjugated imidazo[1,2-a][1,8]naphthyridine-based mesoionic carbene ligand L1, is disclosed. This catalytic protocol is distinguished by its high activity and selectivity, wide substrate scope and modest reaction conditions. A variety of primary amines, RCH2NH2 (R = aliphatic, aromatic and heteroaromatic), are converted to the corresponding amides using ambient air as an oxidant in the presence of a sub-stoichiometric amount of KOtBu in tBuOH. A set of control experiments, Hammett relationships, kinetic studies and DFT calculations are undertaken to divulge mechanistic details of the amine oxidation using 1. The catalytic reaction involves abstraction of two amine protons and two benzylic hydrogen atoms of the metal-bound primary amine by the oxo and hydroxo ligands, respectively. A β-hydride transfer step for the benzylic C-H bond cleavage is not supported by Hammett studies. The nitrile generated by the catalytic oxidation undergoes hydration to afford the amide as the final product. This journal is

Several classes of biologically occurring fatty acid amides have been reported from mammalian and plant sources. Many amides conjugated with fatty acids of mammalian origin exhibit specific activation of individual receptors. Their potential as pharmacological tools or as lead compounds towards the development of novel therapeutics is of great interest. Hence, access to such amides by a practical, high-yielding and scalable protocol without affecting the geometry or position of sensitive functionalities is needed. A protocol that meets all these requirements involves activation of the corresponding acid with carbonyl diimidazole (CDI) followed by reaction with the desired amine or its hydrochloride. More than fifty compounds have been prepared in generally high yields.

A green, one-pot approach based on the solvothermal amidation of carboxylic acids with amines has been developed for the synthesis of diverse aliphatic and aromatic amides. It does not require the use of catalysts or coupling reagents and it occurs in the presence of ethanol that has been proved to have a key role in the process. The proposed strategy is also extendable to biologically active amides and could represent a low-cost and waste-less alternative to the common synthetic pathways.

N-Acyl amino acids directly bind mitochondria and function as endogenous uncouplers of UCP1-independent respiration. We found that administration of N-acyl amino acids to mice improves glucose homeostasis and increases energy expenditure, indicating that this pathway might be useful for treating obesity and associated disorders. We report the full account of the synthesis and mitochondrial uncoupling bioactivity of lipidated N-acyl amino acids and their unnatural analogues. Unsaturated fatty acid chains of medium length and neutral amino acid head groups are required for optimal uncoupling activity on mammalian cells. A class of unnatural N-acyl amino acid analogues, characterized by isoindoline-1-carboxylate head groups (37), were resistant to enzymatic degradation by PM20D1 and maintained uncoupling bioactivity in cells and in mice.
