Problems solved by technology

[0006] The second object of the present invention is to provide a kind of preparation method of monolauric acid glyceride, under nitrogen or carbon dioxide condition, glycerol and lauric acid are prepared the method for monolaurin glyceryl ester by esterification at high temperature, and this method does not use Catalyst, no phosphate is produced during the reaction process, no pollution to the environment, and solves the environmental pollution caused by the discharge of phosphate produced by traditional processes. Since the reaction equipment is fully enclosed, it is environmentally friendly, and the recycled glycerin produced is recycled as The reactants of the next reaction can reduce the production cost

Abstract

The invention discloses a preparation device of glycerol monolaurate and a method thereof, and a control system and a method thereof. According to the preparation device of the glycerol monolaurate, acomputer adopts 14-point temperature acquisition, 8-point pressure acquisition and 1-point PH acquisition, and meanwhile, the opening degree of 14 valves is controlled. The preparation device of glycerol monolaurate is high in automation level and comprehensive and accurate in acquired data, multi-dimensional analysis and control of temperature, pressure and PH are performed, and product qualityand production efficiency are improved. The preparation method comprises the following step: under a nitrogen or carbon dioxide condition, reacting glycerol and lauric acid through an esterification reaction at high temperature for preparing glycerol monolaurate, no catalyst is used, no phosphate is generated, no pollution is caused to the environment, reaction equipment is totally closed and environmentally friendly, and the generated recovered glycerol is recycled to serve as a reactant of the next reaction, so that the production cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a preparation device, method, control system and method of monoglyceride laurate. Background technique [0002] Monolauric acid monoglyceride, also known as monododecanoic acid, has a molecular formula of C 11 h 23 COOCH 2 CHOHCH 2 OH, a lipophilic nonionic surfactant, is a compound naturally occurring in some plants. After extraction, it is often added to food, daily necessities or cosmetics as a fungicide and anti-inflammatory agent. Monoglyceryl laurate with a monoester content of more than 96% has excellent performance in food preservation and emulsification, and is not limited by pH, and still has a good antibacterial effect under neutral to slightly alkaline conditions , Studies have shown that monoglyceride laurate has a good inhibitory effect on bacteria, molds, yeasts, fungi and other microorganisms. [0003] In the method for preparing monogl...
