Description

е Изобретение относитс  к способу получени  диэфиров гликолей и трифто уксусной кислоты общей формулы c fjOdodHz- fti)-dHododFj (j где R- - Rij-H, CH.J, n О, 1, которые могут быть использованы в качестве пластифицирующих, смазочны реагентов, биологически активных препаратов и т.д. Известен способ получени  диэфиров гликолей и триФторуксусной кис .лоты взаимодействием замещенных тет рагидрофуранов, в частности 2,5 лиметилтетрагидрофурана , с избытком трифторуксусного ангидрида при В течение 30 ч, при этом давление понижают с 4,9 до 1,2 эта Ю . Недостатками этого способа  вл ютс  необходимость использовани  не удобного в обращении трифторуксусного ангидрида (т.кип. ), проведение процесса при повышенных температурах и давлении. Наиболее близким к предлагаемому способу  вл етс  способ получени  диэфиров гликолей и триФторуксусной кислоты взаимодействием этиленгликол  с трифторуксусным ангидридом или триФторуксусной кислотой при 0°С в течение 12-214 ч 12 . Недостатком этого способа  вл етс  необходимость охлаждени  реакционной смеси. Целью изобретени   вл етс  упрощение процесса. Поставленна  цель достигаетс  тем, что при осуществлении способа получени  диэфиров гликолей и триФторуксусной кислоты формулы I этерификацией кислородсодержащего соединени  триФторуксусной кислоты вThe invention relates to a process for the preparation of glycol and trifto acetic acid diesters of the general formula c fjOdodHz-fti) -dHodFj (j where R is Rij-H, CH.J, nO, 1, which can be used as plasticizing, lubricating , biologically active preparations, etc. The known method of producing diesters of glycols and triFluoroacetic acid by reacting substituted tetrahydrofurans, in particular 2.5 methyltetrahydrofuran, with an excess of trifluoroacetic anhydride at Within 30 h, while reducing the pressure from 4.9 to 1.2 This Yu. The disadvantages of this sp The need to use trifluoroacetic anhydride (bp), carrying out the process at elevated temperatures and pressures is especially necessary. ° C for 12-214 h 12. The disadvantage of this method is the need to cool the reaction mixture. The aim of the invention is to simplify the process. This goal is achieved by the fact that, in carrying out the method for producing glycol and trifluoroacetic acid diesters of the formula I, by esterifying an oxygen-containing compound trifluoroacetic acid in
