Abstract
The invention discloses a synthetic process of hydrogenized tallow amine polyoxyethylene ether. According to the synthetic process, hydrogenized tallow amine and ethylene oxide are used as raw materials and synthesized into polyoxyethylene ether under the action of a catalytic agent. The synthetic process is characterized in that the ethylene oxide is averagely divided into two parts, one part of the ethylene oxide and the hydrogenized tallow amine are reacted under the action of the catalytic agent of concentrated sulfuric acid for three hours at the temperature of 165 DEG C at the material stirring speed of 100r/min, then the materials are discharged and subjected to standing for two hours at normal temperatures, and then the other part of the ethylene oxide is added to be continuously reacted for three hours at the temperature of 165 DEG C at the rotation speed of 100r/min to obtain the hydrogenized tallow amine polyoxyethylene ether. The synthetic process has the advantages that the ethylene oxide is averagely divided into two parts to be added to a reaction system, the concentrated sulfuric acid serving as the catalytic agent accelerates polymerization reaction so that polymerization reaction time is shortened to only six hours, and the obtained hydrogenized tallow amine polyoxyethylene ether is faint yellow, clear and transparent.
Description
Technical field
The invention belongs to the organic synthesis field, specifically a kind of synthesis technique of hydrogenated tallow amine Soxylat A 25-7.
Background technology
The hydrogenated tallow amine Soxylat A 25-7 has another name called primary octadecylamine polyoxyethylene ether, is a kind of special nonionogenic tenside that the reacting ethylene oxide by hydrogenated tallow amine and different ratios forms.This product has good emulsification, level dyeing performance, and is stable to acid, alkali and performance of hard water, as levelling agent and the static inhibitor of the textiless such as silk, hair, fiber crops, also is used to household sprays, weedicide, sterilant, indoor decoration thing washing composition etc. by widely.CN101125819A discloses a kind of synthetic method of primary octadecylamine polyoxyethylene ether, react by two-stage polymerization, first primary octadecylamine and ethylene oxide segment are not being had to carry out polyreaction under the catalyst action, adding solid methanol sodium catalyst and remaining oxyethane carries out after polymerization and obtains primary octadecylamine polyoxyethylene ether again, the product lighter color that the method obtains, pure transparent clearly, but synthesising reacting time is long, average out to 10-30 hour.
Summary of the invention
The synthesis technique that the purpose of this invention is to provide a kind of hydrogenated tallow amine Soxylat A 25-7 rapidly and efficiently.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of synthesis technique of hydrogenated tallow amine Soxylat A 25-7, take hydrogenated tallow amine and oxyethane as raw material, synthetic Soxylat A 25-7 under catalyst action, it is characterized in that: oxyethane is divided into two parts, first with a oxyethane and hydrogenated tallow amine, react under the concentrated sulfuric acid catalyst effect, material stirring speed is 100r/min, and temperature of reaction is 165 ℃, discharging behind the reaction 3h, normal temperature leaves standstill 2h, adds another part oxyethane again, continues the rotating speed with 100r/min, 165 ℃ thermotonus 3h obtains product hydrogenated tallow amine Soxylat A 25-7.
Preferably, the mol ratio of described hydrogenated tallow amine and oxyethane is 1:1.5, and the concentrated sulfuric acid catalyst consumption is to account for 2.5 ‰ of total quality of material.
The invention has the advantages that: by reinforced method of two steps, oxyethane is divided equally into two parts adds reaction system in batches, accelerating polyreaction take the vitriol oil as catalyzer carries out, shortened the reaction times, polyreaction only needs 6 hours, and the hydrogenated tallow amine Soxylat A 25-7 of gained is faint yellow, clear.
