Description
Высока склонность терпенов к нзоморизацип под действием нгп-рева , окислителей п других факторов позвол ет рассчитывать па возможпость соединени с малепновы.м ангидридом не только тех терпенов, которые заведомо имеют сопр женные двойные св зи, но п терпенов, которые в обычном своем виде таких св зей не имеют. Действительно, нинен , например, и другие тернепы дают при нагреваннн соеднненн с малеиновым ангидридом, онисанные во многих патентах.The high tendency of terpenes to behave under the influence of ngprev, oxidizing agents and other factors makes it possible to calculate the possibility of combining with small anhydride not only those terpenes that obviously have conjugated double bonds, but n terpenes, which in their usual form are have no communications. Indeed, for example, ninne and other ternepa give, when heated, with maleic anhydride, they are found in many patents.
Предлагаетс использовать это свойство терпена дл по.чучеии спирта растворимы.х смол, путе.м соединени живицы или скии1;дара, или пинепа, тернинена, мирцена с малеиновым ангидридом, с последующи .м введением в соединение мочевины. Получаема при это.м красновата , тверда , хрупка смола отлично растворима в спиртах и дает нрн высыхании нрочпые, светлые, эласт 1чпые и блест щие пленки.It is proposed to use this property of terpene to dissolve alcohol soluble resin, by combining resin or skii1; gift, or pinepa, terniena, myrcene with maleic anhydride, followed by the introduction of urea into the compound. The resulting m. Is reddish, hard, brittle resin is very soluble in alcohols and gives a high drying, soft, light, elastic 1pc and glossy film.
Пример. 50 г пинена нагревают в течение 2 час при температуре 160-170° с 36 г малеинового ангидрида, после чего добавл ют к сплаву 22 г мочевины и продолжают варку еще 3-5 час. Полученную смолу раствор ют в спирте, получа готовый сниртов1, .так.Example. 50 g of pinene is heated for 2 hours at a temperature of 160-170 ° C with 36 g of maleic anhydride, after which 22 g of urea is added to the alloy and cooking is continued for an additional 3-5 hours. The resulting resin is dissolved in alcohol to produce a ready-made 1, so.
Предмет изобретени Subject invention
Способ получени лаковых смол па основе продуктов взаи.модействи терпеновых углеводородов с малеиновым ангидридом, отличающийс тем, что, в цел х получени спирторастворимой смолы, к сплаву живицы, скипидара, пин-ена, терпинена или мирцена е малеиновым ангидридом добавл ют мочевину и подвергают далы1е11шему пагреванию .The method of producing lacquer resins on the basis of products of the interaction of terpenic hydrocarbons with maleic anhydride, characterized in that, in order to obtain a soluble resin, urea is added to the resin resin, turpentine, pinipene, terpinene, or myrcene, and maleic anhydride is added to urea and subjected to sulfur fading.
