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.

Single-Site Molybdenum Catalyst for the Synthesis of Fumarate

The catalysts with well-defined mononuclear active sites are expected to develop more active catalytic systems for the key chemical transformations. But the rational design of catalyst with stable mononuclear Mo site is still a crucial challenge because of its oligomerization tendency under reaction condition. Herein, Molybdenum catalyst (Mo-8-HQ) with single Mo sites was designed via the pyridine nitrogen and oxygen in hydroxyl of 8-hydroxyquinoline coordinated with Mo atom. The crystal catalyst was stabilized by π-π stacking interaction and hydrogen bonds to form isolated Mo specie. The single-site molybdenum catalyst exhibited excellent catalytic performance in didehydroxylation reactions with high selectively of dibutyl fumarate (86 %) product at mild reaction condition. Deuterium isotopic studies demonstrated that the mechanism feature of didehydroxylation reaction catalyzed by Mo-8-HQ was through concerted cleavage of two C?O bonds process, which could be accelerated by single-site molybdenum catalysts with electron-rich Mo centers.

Retention Characteristics and Sorption Enthalpies of Esters of Natural Hydroxycarboxylic Acids on DB-1 Stationary Phase

Abstract: Sorption characteristics and retention of esters of glycolic, lactic, malic, and tartaric acids with C1?C8 alcohols of linear structure are studied by gas-liquid chromatography in the temperature range of 90?260°C on DB-1 nonpolar phase. The values of the retention indices of the compounds studied are obtained. On the basis of experimentally determined retention times, the thermodynamic characteristics of sorption under the conditions of limiting dilution are estimated. The dependences of the change in sorption enthalpies on the length of the linear alkyl substituent and on the value of the logarithmic retention index are found. The possibility of estimating the energy of intermolecular interactions of lactic acid esters in the liquid phase is shown on the basis of the obtained values of sorption enthalpies and vaporization enthalpies.

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.
