i;i;
Известны различные способы полученшт глицериновых и нентаэритритовых эфнрог. канифоли (смол ных кнслот) путем этернфнкации смол ных кнслот нли канифоли глицерином или нентаэрнтритом. Процесс провод т путем нагревани канифолн нлп смол ных кислот с соответствующими многоатомными спиртами нри температурах пор дка 240- .Various methods are known for preparing glycerol and non-erythritol compounds. rosin (resin knots) by etherification of the resin knots of nli rosin with glycerin or non-organic. The process is carried out by heating rosin nlp resin acids with the corresponding polyhydric alcohols at temperatures of about 240-.
С целью упрощени процесса п снижени стоимости целевых продуктов, предлагаетс этерифнцпровать канифоль (смол ные кислоты ) глицерином или пентаэритритом непосредственно в осветленной н растворенной в скипидаре живице без предварительного уваривани канифоли. Живица-терпентин из отстойника подаетс в этерификатор, туда добавл етс глицерин или нентаэритрит в необходимом дл этерификацпи количестве, а именно: глицерин - в полуторакратном избытке от теоретического, пентаэритрит - с избытком 10%.In order to simplify the process of reducing the cost of the target products, it is proposed to esterify rosin (resin acids) with glycerol or pentaerythritol directly in the clarified resin and turpentine dissolved in turpentine without prior boiling down the rosin. Turpentine resin from the settling tank is fed into the esterifier, glycerol or nentaerythritol is added thereto in the quantity required for esterification, namely: glycerin - in one and a half times excess from theoretical, pentaerythritol - in excess of 10%.
Процесс провод т при 280-290С при посто нном неремещивании в токе СОо. Прл этерификации происходит отгонка воды п скипидара с примесью глицерина. В остатке иолучаЕот канифольные эфиры. Глицериновый эфир канифолн, полученный но новому способу пз терпентина, на 2-3 маркп светлее эфнров , полученных пз канифоли. По прочпм показател м качество получаемых эфиров удовлетвор ет требовапи м ГОСТа. Скпппдар собг .раетс в сборнике вместе с канифольными маслами, водой и глицерином и нри отстаивании легко отдел етс от них. Такой скипидар может быть использован дл териентинироваип живицы. При перегонке его с вод ным иа|10м получают скииидар, соответствуюпии требовани м ГОСТа.The process is carried out at 280-290C with constant non-displacement in a current of COO. After esterification, distillation of water and turpentine with admixture of glycerin takes place. In the balance of ioluchaEot rosin ethers. Glycerol ester of rosin, obtained by the new method of pz turpentine, is 2-3 lighter in color than the results obtained by ps of rosin. According to quality indicators, the quality of the esters obtained satisfies the requirements of GOST. Scrippdar Sobr. Is collected in a collection along with rosin oils, water and glycerin, and settling is easily separated from them. Such turpentine can be used for the turpentine resin. By distilling it with water and 10 m, sciidar is obtained according to the requirements of GOST.
Новый сиособ не требует специальных уста новок п может быт1 (осуществлен на имеющей с аииарат ре. Осунествленне его позвол ет исключить операции, св занные с варкой и приготовлеппем канифолн, и таким образом сократить затраты производства при получе НИИ эфиров канифолн.The new method does not require special installations; it can be 1 (carried out on a device that has air conditioning). It allows you to eliminate the operations associated with boiling and cooking rosins, and thus reduce production costs when obtaining research institutes of rosin esters.
Предмет изобретени Subject invention
Способ получени эфиров канифоли, напри мер глпцериновых п пентаэритритовых, путем этерификации смол ных кислот соответствую щими многоато гными спиртами, отличающий5 с тем, что. с целью уирон1енн процесса г снижени стоимости целевых продуктов, этерифпкацпю провод т непосредственно в живице с одновременно отгонкой скипидара.The method of producing rosin esters, for example, glpcerin pentaerythritol esters, by esterification of resin acids with the corresponding polyhydric alcohols, 5 characterized by the fact that. in order to process the process of reducing the cost of the target products, this etherification is carried out directly in the resin and at the same time the turpentine is distilled.
