Description
Как известно, ) искусственные маслорастворимые смфлы получаютс путем конденсации фенолов,альдегидов и канифоли .As is known, artificial oil-soluble smfly are obtained by condensation of phenols, aldehydes and rosin.
Предлагаемый сцособ получени искусственных маслорастворимых смол состоит в. конденсации канифоли или ее кислот с альдегидами с возможной последующей этерификацией конденсата с глицерином, в присутствии соответствующих катализаторов или без них, .исключа применение фенолов в процессе конденсации. В результате точка разм гчени конденсатов по сравнению с исходными продуктами в среднем повышаетс на 40°.The proposed method for producing synthetic oil-soluble resins consists of. condensation of rosin or its acids with aldehydes with possible subsequent esterification of condensate with glycerin, in the presence or absence of suitable catalysts, except the use of phenols in the condensation process. As a result, the softening point of condensates rises by 40 ° as compared with the initial products.
-По видоизмененному способу конденсации подвергают эфиры смол ных кислот канифоли с альдегидами./- According to the modified condensation method, esters of resin acids of rosin with aldehydes are subjected. /
Пример 1. 100 частей канифоли с точкой разм гчени по Кремер-Сар,нову в 60° нагревают: с 27 част ми формальдегида при температуре в 110-115° в присутствии 0,1% сол ной кислотыExample 1. 100 parts of rosin with a Kramer-Sar softening point, new at 60 °, are heated: with 27 parts of formaldehyde at a temperature of 110-115 ° in the presence of 0.1% hydrochloric acid
в течение 6 часов. Продукт, . получа-, ющийс в результате - конденсации, растворим в Mac.ijte и имеет точку разм гчени около 100° по Кремер-Сарнову.within 6 hours. Product,. the resulting condensation is soluble in Mac.ijte and has a softening point of about 100 ° Kremer-Sarnov.
Пример 2. Конденсат, полученный по способу, указанному в примере 1, этерифицируетс с глицерином обычным образом./Example 2. The condensate obtained by the method indicated in Example 1 is esterified with glycerol in the usual manner. /
Пример 3. 100 частей глицериноврго эфира смол нь/ с с точкой разм гчени по Кремер Сарнову в 65° нагревают с 26 част ми формальдегида при температуре в 110-115° в присутствием 0,196 сол ной кислоты в течение 6 час. Продукт, получающийс в результате конденсации, растворим в. масле и имеет точк плавлени по Кремер - Сарнову около 105°.Example 3. 100 parts of glycerin ester tar / s with a Kremer Sarnov softening point of 65 ° are heated with 26 parts of formaldehyde at a temperature of 110-115 ° in the presence of 0.196 hydrochloric acid for 6 hours. The condensation product is soluble in. oil and has a Kremer - Sarnov melting point of about 105 °.
