Synthesis of poly(ethyl acrylate-co-allyl acrylates) from acrylate mixtures prepared by a continuous solvent-free enzymatic process

Photoreactivity of Oil and Alcoholic Diterpenic Varnishes: Key Role of the Polymerization Process

“…Such interpretation is strengthened by the fact that the ester bonds of glycerides do not photochemically react at λ > 300 nm as other aliphatic polyesters. [65] The apparition of peresters (1780 cm À 1 ) and esters (C=O stretching 1735 cm À 1 , CÀ O stretching around 1250-1150 and 1020 cm À 1 ) [53,66] increased during the phase 1 of irradiation. Such evolution indicates similar reactions to those described for alcoholic varnishes with MAG, DAG, fatty acids as possible reactive alcohols or carboxylic acids and classical photolysis of glycerides.…”

Entrapment in polymeric material of resting cells of Aspergillus flavus with lipase activity. Application to the synthesis of ethyl laurate

“…avus, 19.8 mg of poly(vinylpyrrolidone) and 7.89 mg of ascorbic acid at 50 C (ref. 40) and tted with a PTFE-lined cap. The reaction mixture was stirred for 18 h at 70 C. Each PAAF containing resting cells was recovered and washed 3 times with deionized water and hexane.…”

Combining a flow reactor with spray dryer to allow the preparation of food-grade quality sodium 2-polyhydroxyalkyl-1,3-thiazolidine-4-carboxylates with a low environmental impact

“…Such systems have many advantages, such as efficiency, simplicity, facile automation, reproducibility, and process reliability by an accurate control of reaction conditions. [22][23][24][25] To achieve our purposes, water and sodium hydroxide were used as the solvent and base, respectively, to obtain TCAs from formaldehyde and aldoses. Moreover, sodium hydroxide in equimolar amount with L-cysteine and aldoses was used in order to obtain the TCAs as sodium salts.…”
