Ethyl Octanoate, as a sucrose by-product, is a polyalcohol-type non-ionic surfactant with excellent performance, security, non-toxicity, no peculiar smell, no contamination, no side effects, no irritability to the body, great security, and also total biodegradability representative. It can successfully reduce the surface stress of water, as well as has superb performance in wetting, dispersing, solubilizing, frothing, emulsifying, and detergency. At the same time, it also has insecticidal and also anti-bacterial residential or commercial properties. As a result, it has solid versatility and a variety of applications. Presently, it has actually been commonly made use of in food market, daily chemical industry, pharmaceutical sector, fabric, agriculture as well as animal husbandry and also other areas, particularly as emulsifier, dispersant, lathering representative, wetting representative as well as cleaner in food industry; daily use Chemical cosmetics, cleaning agents, and so on.
Today invention CN200910029594.8 recommends a new ultrasonic synthesis process of Ethyl Octanoate, and also manufactures high-monoesterified sucrose octanoate with high return. The item has good hydrophilicity and also thermal security. Technical system of the here and now development: a sort of ultrasonic synthesis method of octanoic acid sucrose ester, take sucrose and octanoic acid ethyl ester as basic material, potassium carbonate is as stimulant to accomplish acylation reaction, the molar proportion of sucrose as well as octanoic acid ethyl ester is 2-2.5: 1, with Dimethyl sulfoxide is the response solvent, the substrate sucrose focus is controlled to be 1mol/L, the response temperature is 70-80 ° C, the driver make up 9%-13% of the mass fraction of ethyl octanoate, and the reaction stress is 11kPa. Ultrasonic response in an ultrasonic cleanser with a power of 100W as well as a functioning regularity of 40KHz for 2h. After the reaction coatings, the majority of the solvent is evaporated under reduced pressure, and the purification residue is dissolved in sodium chloride solution as well as n-butanol remedy with a mass focus of 25% under mixing, and the V/V=1:1 of sodium chloride solution: n-butanol, liquid splitting up, the organic stage was cleaned two times with a small amount of water, dried out over anhydrous Na2SO4, as well as the solvent was eliminated, as well as the deposit was cleaned two times with ethyl acetate, after that dried out in vacuo at 45 ° C to consistent weight to get a white waxy strong with a yield of 75 % of sucrose octanoate. CN200910029594.8 manufactured Ethyl Octanoate with a high return by embracing an eco-friendly synthesis innovation. This method not only significantly shortens the reaction time, however also has high reaction selectivity, and also the material of monoester in the product gets to 92%. The HLB value of the manufactured Ethyl Octanoate is greater than 10, which has good hydrophilicity as well as great thermal stability, and can exist stably listed below 150 ° C.
