Description

Д.ЧЯ получени  лаковых смол из фенолов сланцевого масла обычно используют фенолы, выделенные из легкого сланцевого масла. На основе выеокоалкнлированных фенолов, выделенных из среднего илн т желого сланцевого масла, не удавалось ранее получить маслорастворимые смолы из-за высокой в зкости и реакционной способности этих фенолов.D. CHY of obtaining lacquer resins from shale oil phenols usually use phenols isolated from light shale oil. Based on highly compounded phenols isolated from medium or heavy slate oil, it was not possible to obtain oil soluble resins earlier due to the high viscosity and reactivity of these phenols.

Опиеывае.мый способ заключаетс  в том, что сланцевые фено.ты, выделенные из среднего или т желого сланцевого Масла, сплавл ют с обычиы .м синтетическим фенолом в различных соотношени х (от 25 до 65% сланцевых фенолов на оксибензол ), и затем смееь фенолов конденсируют с формальдегидом.An alternative method is that shale fools isolated from medium or heavy shale oil are fused with ordinary synthetic phenol in various ratios (from 25 to 65% shale phenols to oxybenzene), and then dyed phenols condense with formaldehyde.

С целью удалени  масс.-( и тгейтральных кислородных соединений, смееь феиолов перед коидеисацией обрабатывают бензином.In order to remove the masses .- (and the tegateral oxygen compounds, sweeten with faiols, they are treated with gasoline before coideisation.

Синтетические смо.ты, получаемые из смеси сланцевых фенолов с обычным фенолом, могут быть иснользованы дл  производства масл иых лаков .Synthetic resins produced from a mixture of shale phenols with conventional phenol can be used to produce oil lacquers.

Пример. Смесь, состо щую из 50 ч. фенола и 50 ч. фенолов, полученных из т желого еланцевого масла , нодвергают конденсации с 70 ч. форлгалина (37%) в присутствии 2 ч. щавелевой кислоты. К.онденсацию ведут в течение 2 часов при темнерату ре 95-100°. Полученную смесь нромывают гор чей водой и обезвоживают нагреванием до температуры 150°. Смола хороию раствор етс  в масле.Example. A mixture consisting of 50 parts of phenol and 50 parts of phenols obtained from heavy oil of tainan oil is condensed with 70 parts of forlgalin (37%) in the presence of 2 parts of oxalic acid. Condensation is carried out for 2 hours at a temperature of pe re 95-100 °. The resulting mixture is sprinkled with hot water and dehydrated by heating to a temperature of 150 °. Resin is well dissolved in oil.

Предмет изобретени Subject invention

1.Способ получени  феполальдегидных маслорастворимых смол на основе фенолов и формальдегида, о тл и ч а ю щ и и с   тем, что, с це.тью расширени  сырьевой базы, к обычному синтетическому илн камеиноугольному фенолу добавл ют 25- сланцевых фенолов, выделенных из ереднего и т желого масла, после чего с.месь фенолов подвергают конденсации с формальдегидом.1. A method for the production of fepalaldehyde oil-soluble resins based on phenols and formaldehyde, o and t and the fact that, with the expansion of the raw material base, 25 shale phenols isolated from Front and heavy oils, after which the mixture of phenols is condensed with formaldehyde.

2.Прием выно.чиени  способа но п. 1, о т л и ч а ю ш и и с   тем, что, с целью удалени  масел и нейтральных киелородиых соедине1н й, смесь фенолов обрабатывают бензином, после чего оставшиес  фенолы нодвергают конденсации.2. Acceptance of the method of p. 1, about tl and h and w and so that, in order to remove oils and neutral compounds of the body, the mixture of phenols is treated with gasoline, after which the remaining phenols decompose.
