Usage

General Description

DL-Malic acid di-n-butyl ester, also known as dibutyl malate, is a chemical compound derived from malic acid, a naturally occurring compound found in fruits and vegetables. It is commonly used as a flavoring agent and fragrance ingredient in the food and cosmetic industries. This ester is a clear, colorless liquid with a fruity odor and is soluble in most organic solvents. It is used to impart a fruity, apple-like flavor to food products and is also used in fragrance and personal care products. Additionally, it is utilized as a plasticizer in the production of plastics and resins. However, it is important to handle this chemical with care, as it may cause irritation to the eyes, skin, and respiratory system if proper safety precautions are not taken.

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.

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.
