Description
Известен способ получени зфиров муравьиной кислоты при взаимодействии спирта и окиси углерода нри температуре 90-110°С и давлении 200 ат в присутствии в качестве катализатора алкогол та натри . Способ основан на использовании дорогого и взрывоопасного металлического натри , работы с которым в масштабе крупного промышленного предпри ти крайне опасна и вызывает значительные технологические трудности.A known method for the preparation of formic acid zools by the interaction of alcohol and carbon monoxide at a temperature of 90-110 ° C and a pressure of 200 atm in the presence of sodium alkoxide as a catalyst. The method is based on the use of expensive and explosive metallic sodium, work with which in the scale of a large industrial enterprise is extremely dangerous and causes considerable technological difficulties.
Цель изобретени - разработка способа производства эфиров муравьиной кислоты, исключающего применение катализатора, получение которого св зано с использованием натри . Это достигаетс благодар тому, что в качестве катализатора взаимодействи спиртов и окиси углерода используют соли, образованные металлами первой группы Периодической системы элементов и слабыми кислотами, например карбонат натри .The purpose of the invention is to develop a method for the production of formic acid esters, which excludes the use of a catalyst whose preparation is associated with the use of sodium. This is due to the fact that salts formed by metals of the first group of the Periodic Table of Elements and weak acids, for example sodium carbonate, are used as a catalyst for the interaction of alcohols and carbon monoxide.
Процесс осуш,ествл ют следуюш,им образом .The process of drying is as follows.
В реактор загружают спирт и катализатор (безводные соли металлов первой группы Периодической системы элементов и слабы.х. кислот), затем туда же подают окись углерода под давлением 25-200 ат. Включают обогрев и перемешивание. Реакцию ведут при температуре 150-200°С. По окончании реакции продукт выгружают и анализ провод тAlcohol and the catalyst are loaded into the reactor (anhydrous salts of metals of the first group of the Periodic Table of the Elements and weak acids), then carbon monoxide is also fed there under a pressure of 25-200 at. Include heating and mixing. The reaction is carried out at a temperature of 150-200 ° C. At the end of the reaction, the product is discharged and the analysis is carried out
хроматографически. Продолжительность опытов 2 час. Результаты опытов приведены в таблице.chromatographically. The duration of the experiments 2 hours. The results of the experiments are given in the table.
