Abstract

The invention provides an anti-emulsification type neutralization device for preparing dioctyl sebacate. The anti-emulsification type neutralization device is characterized by comprising neutralization stirrers, a transfer pipe and a neutralization separator, wherein the bottom of a neutralization reaction chamber is provided with a plurality of stirrers, one side of the lower portion of the neutralization reaction chamber is provided with a transfer pipe, the other end of the transfer pipe is connected with the neutralization separator, and an oil-water distributor and a sand flushing deviceare arranged inside the neutralization separator. Compared with the prior art, by increasing the volume of the neutralization reaction chamber, the full contact time of a catalyst and an alkali liquoris increased, the catalyst is effectively hydrolyzed, so that the catalyst is easier to separate, the oil-water distributor can effectively distribute oil and water, the retention time of the oil andthe water is increased, the sediment at the bottom can be washed by installing a sand flushing device through regular water flow, and the sludge sediment can be prevented from occupying the effectivevolume. An auxiliary bottle filled with a demulsifier is arranged in the transfer pipe, and the demulsification phenomenon can be effectively eliminated by adding 10-20 ppm of demulsifier into a material.

Description

【Technical field】 [0001] The invention relates to the technical field of plasticizer production and processing, in particular to an anti-emulsification neutralization device for preparing dioctyl sebacate. 【Background technique】 [0002] Dioctyl sebacate is an excellent cold-resistant plasticizer, mainly used in polychloroacetic acid cable materials, films, artificial leather and other products, and can also be used as synthetic lubricating oil, precision machinery oil solvent and synthetic rubber softener. [0003] In the preparation process of dioctyl sebacate, neutralization and washing steps are required, and emulsification will occur during the neutralization and washing process. In addition to the serious impact on the subsequent production process, the neutralization of water during emulsification will also occur. The oil content in washing water increases greatly, so the unit consumption of materials is high, and the quality of sewage is seriously deteriorated. [0...
