Abstract

FIELD: organic chemistry. SUBSTANCE: desired polyvinyl ether has units having common formulawhere R,Rand Ris hydrogen or alkyl group, Ris alkylene group, Ris alkyl group and k=0-10. Said ether is prepared by polymerization of vinyl ether. Combination of Bronsted acid, Lewis acid or organometallic compounds with product of addition of water, alcohol, phenol, acetal or vinyl ether to carboxylic acid is used as initiator of said polymerization. Method for production of ether which comprises interaction of acetal or ketal having formulawith hydrogen is also proposed. Said interaction is carried out in the presence of solid catalyst having acid properties and hydrogenation capacity, thus RO or RO are converted into H. EFFECT: improves quality of desired product, improves efficiency of the method.

Предлагается простой поливиниловый эфир, который содержит составляющие звенья, выраженные общей формулой, приведенной в описании, и способ его получения, включающий полимеризацию простого винилового эфира в качестве мономера. В способе используют особый вид инициатора, который представляет собой сочетание кислоты Брэнстеда (апротонной кислоты), кислоты Льюиса или металлоорганических соединений и продукта присоединения воды, спирта, фенола, ацеталя или простого винилового эфира к карбоновой кислоте. Поливиниловый эфир пригоден для использования в качестве смазки и т.п. Предлагается также способ получения простого эфира, включающий в себя введение ацеталя или кеталя, представленного формулой, также приведенной в описании в химическое взаимодействие с водородом в присутствии твердого катализатора, обладающего кислотными свойствами и гидрирующей способностью, для превращения R3 3O - или R3 4O - в H.

A polyvinyl ether is provided which contains constituent units expressed by the general formula given in the description and a process for its preparation, comprising the polymerization of a vinyl ether as a monomer. The method uses a special type of initiator, which is a combination of Bransted acid (aprotic acid), Lewis acid or organometallic compounds and the product of the addition of water, alcohol, phenol, acetal or a simple vinyl ether to a carboxylic acid. Polyvinyl ether is suitable for use as a lubricant and the like. A method for producing an ether is also provided, comprising introducing acetal or ketal represented by the formula also described in the chemical reaction with hydrogen in the presence of a solid catalyst having acidic properties and hydrogenating ability to convert R 3 3 O - or R 3 4 O - in H.
