What is Ethyl Octanoate?

Ethyl Octanoate is a colorless and transparent liquid, periodically with a yellowish color, with a pineapple-like fragrance and wonderful preference. Boiling point 208.5 ℃. Insoluble in water, yet conveniently soluble in ethanol, ether, chloroform, and almost insoluble in propylene glycol. It creates an azeotropic mix with water, with an azeotrope of 98.25 ° C as well as a web content of 18%. It is prepared by home heating octanoic acid as well as ethanol under the catalysis of a small amount of concentrated sulfuric acid. Can be utilized as a flavor agent for orange, strawberry, pineapple and other seasonings. Ethyl Octanoate is a kind of edible spice specified by GB2760-96, which is mostly used to prepare flavors such as milk, cheese, apple and pineapple fruit wine, brandy, rum and so on. It is gotten by esterification of octanoic acid and ethanol.

Ethyl Octanoate Uses

As a sucrose derivative, fatty acid sucrose ester is a safe, non-toxic, odor-free, non-polluting polyol-type non-ionic surface with excellent performance, no side effects, no irritation, good stability, and complete biodegradability. active agent. It can effectively reduce the surface tension of water, and has excellent performance in wetting, dispersing, solubilizing, foaming, emulsifying, and detergency. At the same time, it also has insecticidal and bacteriostatic properties. Therefore, it has strong adaptability and wide application range. At present, it has been widely used in food industry, daily chemical industry, pharmaceutical industry, textile, agriculture and animal husbandry and other fields, especially as emulsifier, dispersant, foaming agent, wetting agent and cleaning agent in food industry; Cosmetics, detergents, etc. in the chemical industry.

The invention CN200910029594.8 proposes a new ultrasonic synthesis process of sucrose caprylate, and synthesizes high monoesterified caprylic acid sucrose ester in high yield. The product has good hydrophilicity and thermal stability. The technical scheme of the present invention: an ultrasonic synthesis method of sucrose caprylate, using sucrose and ethyl caprylate as raw materials, potassium carbonate as a catalyst to carry out acylation reaction, the molar ratio of sucrose and ethyl caprylate is 2-2.5:1, with Dimethyl sulfoxide was used as the reaction solvent, the substrate sucrose concentration was controlled at 1 mol/L, the reaction temperature was 70-80 °C, the catalyst accounted for 9%-13% of ethyl octanoate, and the reaction pressure was 11kPa under the condition of The ultrasonic reaction was carried out for 2h in an ultrasonic cleaner with a power of 100W and an operating frequency of 40KHz. After the reaction, most of the solvent was evaporated under reduced pressure, and the distillation residue was dissolved in a sodium chloride solution with a mass concentration of 25% and a n-butanol solution under stirring. The sodium chloride solution: n-butanol V/V=1:1 , the liquids were separated, the organic phase was washed twice with a small amount of water, dried over anhydrous Na2SO4, and the solvent was removed. After the residue was washed twice with ethyl acetate, it was vacuum-dried at 45°C to constant weight to obtain a white waxy solid with a yield of 75%. % Sucrose Caprylate. CN200910029594.8 adopts green synthesis technology to synthesize sucrose octanoate with high yield. This method not only greatly shortens the reaction time, but also has high reaction selectivity, and the content of monoester in the product reaches 92%. The HLB value of the synthesized sucrose caprylate is greater than 10, has good hydrophilicity and good thermal stability, and can exist stably below 150°C.

Preparation of Ethyl Octanoate

The esterification reaction is generally a reversible reaction. In order to improve the yield of the ester, it is necessary to separate one component from the product or to make one of the components in the reactant excess so that the reaction proceeds in a positive direction. In the prior art, the method of distillation is mostly used to steam out the water in the product, thereby improving the yield of the product. However, this method consumes a lot of heating energy, which is not conducive to energy saving. The utility model CN201320461083.5 provides a rectification device for producing Ethyl Octanoate in order to overcome the above-mentioned technical problems, which can easily remove the water in the product during the reaction process, so as to achieve the purpose of improving the yield of the product. The technical scheme for solving the above-mentioned technical problems is as follows: a rectifying device for producing Ethyl Octanoate includes a rectifying tower column body, a reboiler and a condenser, and is characterized in that a guide pipe is also provided at the outlet of the condenser. Fig. 1 is the structural representation of the utility model; Fig. 2 is the structural representation of the rectifying tower in the utility model; Among the figures: 1 is the tower body, 2 is the condenser, 3 is the reboiler, 4 is the guide pipe, 11 It is the steam outlet, 12 is the reflux liquid inlet, 13 is the spray device, 14 is the packing, 15 is the return port of the reboiler, and 16 is the material inlet.

In the technical scheme of the utility model, the rectification tower adopts a packed tower, which can fully mix the reactants, and the metal corrugated structured packing has the characteristics of small resistance, uniform gas-liquid distribution, high efficiency, large energy, and insignificant amplification effect, and has the advantages of high efficiency. , pressure drop and the advantages of large flux. The tube-and-tube heat exchanger has a relatively simple, compact and inexpensive structure, which can reduce operating costs. A guide pipe is set at the outlet of the condenser. Since the product Ethyl Octanoate is insoluble in water and its mass is lighter than water, the condensate at the outlet of the condenser is in two phases of water and oil. In order to ensure that the reaction proceeds in the positive direction, during the reaction process, the water in the product is drawn out by the guide tube, and no longer participates in the reflux reaction. Therefore, the reaction time can also be reduced, manpower and material resources can be saved, and the yield of the product Ethyl Octanoate can be improved at the same time.
