Paragraph 0044; 0049; 0050, (2018/11/22)
The invention provides a micromolecular gelator, a gel material, a preparation method and an application. The gelator is prepared by taking cheap and easily available phenyllactic acid as a raw material and introducing a hydrazide group and a hydrophobic alkyl chain through a simple and mature chemical reaction. The gelator can effectively gelate various organic solvents; the gel material formed by the gelator and methyl benzoate can quickly and efficiently remove phenol from sewage; the gelator can selectively gelate petroleum products such as gasoline, diesel oil, kerosene and lubricating oil, and crude oil in an oil-water mixture without the help of an additive; oil and water separation is achieved by simple operation; the gelator can be used for leakage management of the crude oil andthe petroleum products and is multifunctional; and in addition, the gelator has good recyclability and very good application prospects in the fields of phenol removal from the sewage, marine oil spilltreatment and the like.
Synthesis of new chiral ionic liquids from α-hydroxycarboxylic acids

experimental part, p. 294 - 299 (2011/05/17)
New functionalized optically active N-methylimidazolium ionic liquids with an asymmetric center at the β-position to the imdazole ring were synthesized as bromide salts from optically active α-hydroxycarboxylic acids. The bromide anions were exchanged by carboxylate anions with Amberlite IRA 400 ionic exchange resin.
Zinc-catalyzed enantiospecific sp3-sp3 cross-coupling of α-hydroxy ester triflates with grignard reagents

(Chemical Equation Presented) Zinc chloride does the trick and efficiently catalyzes the enantiospecific cross-coupling of α-hydroxy ester triflates with Grignard reagents under mild conditions. Enantiopure α-hydroxy esters are directly available from the chiral pool or by diazotization of α-amino acids. Substantial variations in both reacting partners are tolerated making this methodology an attractive alternative to enolate alkylation featuring a reversal of polarity.
