Preparation method of malate with low chroma and low acid value

The invention discloses a preparation method of malate with low chroma and a low acid value. The preparation method comprises a step (1) of preparing n-butyl malate and a step (2) of preparing long-chain fatty alcohol malate. The method has the advantages that yield is high and reaches 95% or above; a catalyst is cheap and easy to obtain, and the dosage of the catalyst is small and accounts for about 0.5%-2% of the total weight of reaction raw materials; reaction conditions are mild, a reaction temperature does not exceed 140 DEG C, and reaction time is short; the obtained malic acid long-chain fatty alcohol ester is low in chromaticity and acid value and meets commercial standards; and the intermediate n-butyl malate can be used as a commercially available product. The method for preparing the long-chain fatty alcohol malate by adopting an ester exchange method has not been reported in related literatures and has creativity.

Reductive coupling of aldehydes by H2S in aqueous solutions, a C-C bond forming reaction of prebiotic interest

We report here a novel reductive coupling reaction of conjugated, non- or poorly enolizable aldehydes induced by H2S and operative in aqueous solutions under prebiotically relevant conditions. This reaction leads from retinal to β-carotene, and from benzylic aldehydes to the corresponding diarylethylenes. This novel reaction also opens a new potentially prebiotic pathway leading from glyoxylic acid to various compounds that are involved in the reductive tricarboxylic acid cycle. This C-C bond forming reaction of prebiotic interest might have been operative, notably, in the sulfide-rich environments of hydrothermal vents, which have been postulated as possible sites for the first steps of organic chemical evolution.
