Abstract

The invention discloses a rectifying apparatus for producing ethyl octanoate. The apparatus includes a rectifying tower body, a reboiler and a condenser, and the outlet of the condenser is provided with an L-shaped honeycomb duct. The tower top of the rectifying tower is provided with a steam outlet, one side below the steam outlet is provided with a backflow liquid inlet, the backflow liquid inlet is connected with a spraying device, a filler is arranged below the spraying device, the lower end of the filler is provided with a reboiler return opening, and the tower bottom of the rectifying tower is provided iwht a material feeding opening. The outlet of the condenser is provided with the honeycomb duct, ethyl octanoate is insoluble in water and has a lower density than water, and a condensate liquid at the outlet of the condenser has two phases of water and oil. Water in products is separated out through the honeycomb duct in the reaction process and does not participate in a refluxing reaction in order to guarantee the forward implementation of the reaction. The apparatus reduces the reaction time, saves manpower and material resources, and improves the yield of the product ethyl octanoate.

Description

technical field

[0001] The invention relates to the field of chemical equipment, in particular to a rectifying device for producing ethyl octanoate. Background technique

[0002] Ethyl caprylate is an edible spice specified in GB2760-96 that is permitted to be used. It is mainly used to prepare flavors such as milk, cheese, apple and pineapple wine, brandy, and rum. It is obtained by esterification of octanoic acid with ethanol. 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. SUMMARY OF THE INVENTION
