Изобретение относитс  к способу получени  исйвьы iCMemaiHHbix эфир01в дифе/новой KIHCлоты , на ход щдиЧ п;рименение в полимерной пром ы ш л eiHiHOCTH.This invention relates to a method for producing an iCMemaiHHbix ester01 in a diff / new KIHClot, per course of the circuit; it is used in the polymer industry by means of eiHiHOCTH.

Известен способ получени  смешанных эфйр01В фталавой иислоты стутел ооследовательнОго взаимодействи  фталевого ангидрида пр,и .иагграваани  с двум  различными оииртами . Первую стадиЕО об1ра1301ва1ни  мо1ноэфи1ра задут без катализатора -при иа-превании до 160° С, а стад1ию - в И|р исутст вии кислых каталиэатор0 в темп е.р а туре до 160°С.There is a known method for preparing mixed esters of phthalic acid and isotyl stitel about the sequential interaction of phthalic anhydride pr, i.aggravani with two different sources. The first stage of EO11313VA1Ni monoether will be blown out without a catalyst — when it is converted to 160 ° C, and the stage — in the IU of acid catalysts at a rate of 160 ° C.

По П1редлагаам01му способу получают иовые смешанные эфиры Д ифено1вой кислоты, обладающие кратно улучшенными озойствами по с/раиненйю с -HeiBecTinbiiMM.According to the P1 offers, I get i-mixed esters of phenoic acid, which have multiply improved ozoicities along with / HeiBecTinbiiMM.

Указанные соединени  получают последовательной этери фикацией днфенового ангидрида различными снирта1ми при «агревании.

The formation stage of the monoether is treated with dipheno1, which is an ORI | D | p and aa | romat1Icheok1IM, c.I.p. or aliphatic alcohol with a large number of carbon atoms without a catalyst, not more than 1%, and then PIZSH1M alcohol in 1Natural acid catalyst when n-averavial is removed, it is water, and the product is known for its known acid.

В качестве аро)ма1тических и цикличесифтх спиртов .могут попользоватьс  любые, например бенз1иш.авый, цнклогексиловый .и тому подобные , в том числе с заместител ;мн, а в качест1ве ал1ифат1ическнх спиртов - .метиловый, этиловый, ИЗоа1МИловый, 2-этилге«силовый и другие, содержаш,ие до 16 атомов углерода. Получеииые таким образом эфнры меют высокую температуру кипени  и могут использоватьс  в качестве пластификаторов термостойких поли1меров.

Thus obtained efnry have a high boiling point and can be used as plasticizers for heat-resistant polymers. As a quality agent, Kislopny catalysts 1 can use any mineral acids such as apo, mat; other sulfonic acids.
