Usage

General Description

MALEIC ACID MONO(2-ETHYLHEXYL) ESTER, also known as mono-ethylhexyl maleate, is a chemical compound derived from maleic acid and 2-ethylhexanol. It is commonly used as a plasticizer and an intermediate in the production of products such as resins, adhesives, and coatings. This clear, colorless liquid is known for its strong resistance to heat, light, and water, making it a valuable component in various industrial applications. Additionally, it is also used as a reactant in the manufacturing of polymers and as a lubricant additive. However, it is important to handle this chemical with care and ensure proper ventilation and protective equipment when using it, as it can be harmful if inhaled, swallowed, or comes into contact with skin or eyes.

Synthesis of novel amphiphilic compounds containing AZA-12-crown-4 or D-glucosamine and their ion permeability

New amphiphilic compounds (Types 1, 2, and 3) composed of triethylene glycol monomethyl ether, octanol, and aza-12-crown-4 or D-glucosamine were synthesized. Aza-12-crown-4 was connected to an amphiphlic alkyl chain by the -CO-N- linkage in Type 1 and by -C-N- in Type 2, and D-glucosamine was connected to it by -CO-N- in Type 3. The ion permeability of these compounds was elucidated by means of the black lipid membrane method with an alternating current (a,c.). Only Type 2 compound showed significant transmembrane currents when incorporated into the lipid bilayer membrane in aqueous NaCl, KC1, and RbCl solutions.

A comparative study of the thermal properties of homologous series of crystallisable n-alkyl maleate and itaconate monoesters

Homologous series of crystallisable C8-C22 even-numbered alkane oligomers with either maleate or itaconate monoesters end-groups were synthesized. Their total phase change enthalpy (ΔHtpce) and entropy (ΔStpce) on melting, determined by DSC, show a linear dependence with the number of carbons of the alkyl chain. A comparison was performed with corresponding succinate derivatives. The influence of the end functions on ΔStpce was examined in view of ΔStpce values estimated by the group additivity approach. A fair agreement between the experimental and the estimated entropy values could be demonstrated. Thermogravimetric analysis (TGA) has shown that the maleate oligomers are less stable than the corresponding succinate and itaconate derivatives. This behaviour could be confirmed by the activation energies of the degradation process.

The properties of a family of two-headed surfactant systems: The 4- alkyl-3-sulfosuccinates 2. Surface properties of alkyl sulfosuccinate micelles

The micellar properties of a family of two-headed surfactants, the alkyl sulfosuccinates, were investigated employing fluorescence, ultra-violet spectroscopy, and acid-base titrations, as a function of the chain length of the surfactant. Polarity of the micellar interior was investigated using pyrene and the ionic probe 8-anilino-1-naphthalensulfonic acid ammonium salt (ANS). Pyrene I1/I3 ratios were used to probe the microenvironment of the probe in the palisade layer of the micelle. The pK(a) values of both of the anionic head groups were determined using acid-base titrations. Surface potential measurements were obtained from the measurement of the pK(a) of the hydrophobic indicator, 7-hydroxycoumarin, at the sulfosuccinate micellar interface. All of these results were used to examine the surface properties of the alkyl sulfosuccinate micelles and the polarity of the micellar interior.
