Biocatalytic esterification in supercritical carbon dioxide by using a lipid-coated lipase
Mori, Toshiaki,Kobayashi, Atsushi,Okahata, Yoshio
, p. 921 - 922 (1998)
A lipid-coated lipase is soluble and acts as a more efficient catalyst for triglyceride syntheses in supercritical carbon dioxide (scCO2) than in conventional organic solvents, and the reactivity can be controlled reversibly by changing pressure and temperature in scCO2.
4-O-Acetyl-3-O-tert-butyldimethylsilyl-l-rhamnal: a building block in the stereoselective synthesis of 2-deoxy-α-l-rhamnopyranosides

, p. 2702 - 2707 (2006)
The stereoselective synthesis of 2-deoxy-α-l-glycosides by addition of various acceptors to 4-O-acetyl-3-O-tert-butyldimethylsilyl-l-rhamnal promoted by triphenylphosphine-hydrogen bromide is developed.
Enzymatic esterification of lauric acid to give monolaurin in a microreactor
Li, Xin,Miao, Shanshan
, p. 660 - 667 (2021/03/03)
Monolaurin is a naturally occurring compound widely utilized in food and cosmetics. In this paper, we present a new method for the synthesis of monolaurin by esterification between lauric acid and glycerol catalyzed by Novozym 435 using a microreactor. The conversion of lauric acid is 87.04% in 20 min, compared with 70.54% via the batch approach in 5 h. Using an optimized solvent system consisting of t-BuOH/tert-amyl alcohol (1:1, v/v), the selectivity using the microreactor method is enhanced to 90.63% and the space–time yield of the process is 380.91 g/h/L. This newly devised method has the potential for application to other multiphase and enzymatic reactions.

Paragraph 0138-0139, (2017/01/23)
The invention discloses a preparation method for diacylglycero and an intermediate thereof. The preparation method for diacylglycero comprises the following steps: in an ether solvent and/or an alcohol solvent, in the present of an alkali, performing hydrolysis reaction on a compound shown as a formula 5, so as to obtain diacylglycero which is 1 shown in a formula 1. R in the formula 5 and 5 is C14-C18 saturated or unsaturated aliphatic acyl. The preparation method is cheap in raw materials, mild in reaction conditions, safe in operation, simple in postprocessing operation, high in reaction conversion rate, high in yield and suitable for large-scale production.
