Synthesis and thermophysical characterization of fatty amides for thermal energy storage

Nine monoamides were synthesized from carboxylic acids (C8–C18) and crude glycerol. The final monoamides were the result of a rearrangement of the acyl chain during the final hydrogenation process. The purity of the final compounds was determined by spectroscopic and mass spectrometry (MS) techniques. The thermophysical properties of solid monoamides were investigated to determine their capability to act as phase change materials (PCM) in thermal energy storage. Thermophysical properties were determined with a differential scanning calorimeter (DSC). The melting temperatures of the analyzed material ranged from 62.2 ?C to 116.4 ?C. The analyzed enthalpy of these monoamides ranged from 25.8 kJ/kg to 149.7 kJ/kg. Enthalpy values are analyzed considering the carbon chain and the formation of hydrogen bonds.

Chemical synthesis method for OPO structured lipid

The invention discloses a chemical synthesis method for an OPO (1,3-dioleic acid-2-palmitic acid triglyceride) structured lipid. The chemical synthesis method is characterized by comprising the following steps: (a) in the presence of an alkali catalyst, performing heating reflux reaction reduced pressure distillation on 1,3-dichloro-2-propanol and hexadecanoic acid methyl ester in an organic solvent, so as to obtain 1,3-dichloro-2-hexadecanoic acid ester; and (b) further putting sodium oleate into the 1,3-dichloro-2-hexadecanoic acid ester obtained in the former step, introducing nitrogen for protection, putting into a reactor with a backflow condensation device, performing a reaction for 2-5 hours at 50-100 DEG C, performing weak alkali water washing, adjusting the pH value to be neutral, drying, and performing molecular distillation or vacuum distillation, thereby obtaining high-purity OPO. The chemical synthesis method is simple and convenient in synthesis route, simple in after treatment and high in total yield (greater than 75%), and OPO can be synthesized effectively.

A tandem Finkelstein-rearrangement-elimination reaction: a straightforward synthetic route to allyl esters

Allyl esters can be obtained by a Finkelstein-rearrangement-elimination reaction of 2-chloro-1-(chloromethyl)ethyl esters induced by NaI. Sodium iodide can be used below equivalence using a reductive agent as sodium thiosulfate. High yields are obtained with most of the diverse esters studied. The method described avoids the use of allyl alcohol as a reagent. 2-Chloro-1-(chloromethyl)ethyl esters are prepared from glycerol, the main by-product of biodiesel industry. The effectiveness of iodine as reagent to hydrolyze allyl esters is also confirmed.
