Description
Предлагаемое изобретение относитс к способам получени эфиров смол ных кислот с помощью полиглицеринов.The present invention relates to methods for producing esters of resin acids using polyglycerols.
Недостатком глицеринового эфира смол ных кислот вл етс то обсто тельство , что точка плавлени эфира не выше точки плавлени исходного продукта. Повышение точки плавлени эфира сделало бы его более ценным дл получени лаков и пластических масс.A disadvantage of glycerol ester of resin acids is the fact that the melting point of the ester is not higher than the melting point of the starting product. Increasing the melting point of the ether would make it more valuable to obtain lacquers and plastics.
Предлагаемый способ заключаетс в том, что вместо обычного глицерина беретс продукт его полимеризации или в виде глицеринового пека (дестилл ционна смола, получаюш,а с в остатке при дестилл ции глицерина и состо ща главным образом из полиглицеринов) или же в виде полиглйцерина, полученного нагреванием глицерина 15-45 час. при температуре около его точки кипени с обратным холодильником. В зависимости от продолжительности нагрева,The proposed method consists in replacing the usual glycerol with a product of its polymerization or as a glycerol pitch (distillation resin, which is obtained, and with residue in the distillation of glycerol and consisting mainly of polyglycerols) or as polyglycerol obtained glycerol 15-45 hours. at a temperature near its boiling point. Depending on the duration of heating,
получаютс продукты от ди-до гексаглицерина .di-hexaglycerol products are obtained.
Метод выполнени способа, например при абиетиновой кислоте, аналогичен обычному процессу этерификации, например: 100 ч. канифоли и 18 частей полиглицерина нагреваетс при 200-250 до про снени плава. Процесс лучше вести с обратным холодильником и до бавлением катализатора, напр. 0,5% окиси цинка.The method of performing the method, for example with abietic acid, is similar to the usual esterification process, for example: 100 parts of rosin and 18 parts of polyglycerol are heated at 200-250 until clarification of the melt is made. The process is best carried out with a reflux condenser and the addition of a catalyst, for example. 0.5% zinc oxide.
Предмет изобретени .The subject matter of the invention.
Способ получени эфиров смол ных: кислот, охличающийс тем, что канифоль этерифицируют обычными дл получени глицериновых эфиров смол ных кислот приемами с применением в качестве этерифицирующих спиртов - полиглицеринов , получаемых известными способами при нагревании глицерина.A method for producing resin esters: acidified by the fact that rosin is esterified using resin techniques that are common for the preparation of glycerol esters using esterifying alcohols — polyglycerols, which are obtained by known methods by heating glycerol.
