Citrate Ester is colorless or light yellow liquid, can be mixed with acetone, CCl4, mineral oil, acetic acid, castor oil, alcohol and its solvents; insoluble in water, non-toxic, tasteless, small volatility, heat-resistant, light-resistant, water-resistant, and vinyl resins, cellulose acetate, cellulose acetyl butyrate, cellulose ethyl cellulose, benzyl cellulose and other compatibilizers, plasticizing performance is better for the plasticizers; but also anti-bacterial and does not breed bacteria, non-irritating, flame-retardant and degradable. Plasticizer for PVC, chlorinated alkene copolymer, cellulose resin. Good compatibility, high plasticizing efficiency; excellent cold resistance, light resistance, water resistance; low volatility, slightly toxic, mold resistance. It can also be used as a plastic plasticizer for food packaging and medical and health products, children's toys.
The traditional way of citrate production is to put citric acid, alcohol and catalyst into kettle reactor, stirring and heating to carry out esterification reaction, and then neutralization and washing to separate the catalyst after the completion of the esterification reaction, followed by distillation, decolorization and filtration to get the purity of citrate of 99.5% or more. A major disadvantage of using kettle reactor is that it cannot produce continuously, low production efficiency, small heat exchange area of the reactor, the reaction temperature is not easy to control, and the material residence time is not consistent, resulting in non-uniform reaction.
Store under dry inert gas, keep container tightly closed, store in a cool, dry place Packed in galvanized iron drums. Store in a cool, ventilated place. The storage should be dedicated and not mixed with other items. Pay attention to fire prevention. Polymerization inhibitor should be added before storage and transportation.
Before transportation, check whether the packing container is complete and sealed, and make sure the container is not leaking, collapsing, falling or damaged during transportation. Strictly prohibit mixing and transporting with oxidizing agents, acids, alkalis, edible chemicals and so on. The transport vehicle and ship must be thoroughly cleaned and sterilized, otherwise it is not allowed to ship other items. When transported by ship, the fitting position should be far away from bedrooms, kitchens, and isolated from the cabin, power supply, fire source and other parts. Road transportation should follow the prescribed route.
It is a non-toxic plasticizer with strong solubility and good compatibility with many resins, and the products plasticized with it have good oil resistance, it is a non-toxic plasticizer, widely used as plasticizer for cellulose resin and vinyl resin, as bulking and shape-keeping agent in food, it can improve the foaming performance of baked food and improve the bulking state, as antioxidant, it can be used to stabilize the soybean oil, salad oil, margarine, shortening and other edible oils and fats, as aroma enhancer, it can be used in soft drinks and cold drinks, candy, baked food to increase the flavor, and it is also used as chelating agent and carrier solvent.
