Description
Высока склонность терпенов к изомеризации под действием нагрева , окислителей и других факторов позвол ет рассчитывать на соединение с малеиновым ангидридом не только тех терпенов, которые заведомо имеют сопр женные двойные св зи, но и тех, которые в обычном своем виде таких св зей не имеют.The high tendency of terpenes to isomerize under the action of heat, oxidizing agents and other factors makes it possible to rely on the connection with maleic anhydride not only to those terpenes that obviously have conjugated double bonds, but also to those that do not normally have such bonds.
Согласно изобретению, предлагаетс использовать это свойство терпенов дл получени спирторастворимых смол путем соединени живицы или скипидара или пинена, терпинена, мирцена с малеиновым ангидридом с последующим введением в соединение мочевины. Получаема при этом красновата тверда хрупка смола отлично раствор етс в спиртах, дава при высыхании прочные, светлые, эластичные и блест щие пленки.According to the invention, it is proposed to use this property of terpenes to obtain alcohol-soluble resins by combining sap or turpentine or pinene, terpinene, myrcene with maleic anhydride, followed by the introduction of urea into the compound. The resulting reddish, hard, brittle resin is highly soluble in alcohols, giving strong, light, elastic and glossy films upon drying.
Пример. 50 г. пинена нагревают в течение 2 час при температуре 160-170° с 36 3 малеинового ангидрида, после чего добавл ют к сплаву 22 г мочевины, продолжа далее варку еще 3-5 час. Полученную смолу раствор ют в спирте, получа готовый спиртовой лак.Example. 50 g of pinene is heated for 2 hours at a temperature of 160-170 ° C with 36 3 maleic anhydride, after which 22 g of urea is added to the alloy, continuing further cooking for another 3-5 hours. The resulting resin is dissolved in alcohol to form a finished alcohol varnish.
Предмет изобретени Subject invention
Способ получени лаковых смол на основе продуктов взаимодействи терпеновых углеводородов с малеиновым ангидридом, отличающийс тем, что, в цел х получени спирторастворенной смолы, к сплаву живицы, скипидара, пинена, терпигена или мирцена с малеиновым ангидридом добавл ют мочевину и сплав подвергают дальнейщему нагреванию .A method of producing lacquer resins based on the reaction products of terpene hydrocarbons with maleic anhydride, characterized in that, in order to obtain an alcohol-soluble resin, urea is added to the resin resin, turpentine, pinene, terpigena or mycene with maleic anhydride and the alloy is further heated.
