Adding a certain compound to certain chemical reactions, such as: 2807-30-9, 2-Propoxyethanol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 2-Propoxyethanol, blongs to alcohols-buliding-blocks compound. Recommanded Product: 2-Propoxyethanol
example: of pretilachlor, wherein the steps of specific reaction of producing pretilachlor is: Reacting the ethylene glycol monopropyl The present invention comprises a process for the production ether with thionyl chloride to form a chloroether, carried out condensation reaction of chloroether with aniline to obtain a condensation product. The condensed product is distillated to obtain distilled amine ether, and the distilled amine ether is subjected to an acylation reaction to obtain pretilachlor. In the step of producing the chloroether, the thionyl chloride is mixed with the ethylene glycol monopropyl ether by dropwise addition.The step of producing the chlorinated ether is: The ethylene glycol monopropyl ether placed into the reactor, stirring, thionyl chloride was added drop wise. after the completion of drop wise addition the insulation reaction was carried out for 2 hours to produce hydrogen chloride and sulfur dioxide tail gas and chloroether. the mentioned produced chloroether further comprises the step of treating the hydrogen chloride and the sulfur dioxide tail gas, wherein the step of treating the hydrogen chloride and the sulfur dioxide tail gas is: Hydrogen chloride and sulfur dioxide tail gas are absorbed by both water and alkali, hydrogen chloride prepared hydrochloric acid and sulfur dioxide made of sodium sulfite.The step of carrying out the condensation reaction of the chloroether with aniline is: Aniline and chloroether placed into the reactor, raise the reaction temperature using thermal conductive oil , the end of the reaction layers were separated by adding liquid caustic, oil layer into the next distillation step, water layer was drained. The step of distillating the condensed product to obtain a rectified amine ether is: The condensation product is added to the aniline distillation kettle and carried out distillation, an excess of aniline is separated and applied, then amine ether was placed into distillation kettle to carried distillation of amine ether until the acceptance of qualified amine ether and a small amount of high boiling point residue was directly slag discharged.the steps of acylation reaction of distilled amine ether is as follow: after the qualified amine ether was metered it was put into the acylation kettle, and then placed into the solvent of toluene and liquid caustic soda, slowly dropwise added the measured Chloroacetyl chloride and after the completion of the dropwise addition the reaction was incubation for one hour. then it was placed into the water kettle and wash with water. The upper layer into the desolvation process and the water layer to the sewage treatment. the steps of mentioned desolvation process is: the washed pretilachlor and toluene liquid put into the lifting film for desolvation and the solvent into the application appliquer and finally obtained pretilachlor crude oil .
At the same time, in my other blogs, there are other synthetic methods of this type of compound,2807-30-9, 2-Propoxyethanol, and friends who are interested can also refer to it.
