Description

перилена можно использовать по назначению без предварительной очистки.perylene can be used for its intended purpose without pre-treatment.

Предложенный способ имеет следующие преимущества.The proposed method has the following advantages.

Возможность регулировани  среднего молекул рного веса (1000-45000); доступность и дешевизна катализатора; достаточно высокий выход (50-60%) целевых продуктов и простота их выделени .The ability to adjust the average molecular weight (1000-45000); availability and low cost of the catalyst; sufficiently high yield (50-60%) of the target products and ease of their isolation.

Пример 1. В автоклав из нержавеющей стали (V 300 мл) загружают 100 г пиперилена (соотношение транс : цис - 4 : 56), добавл ют 0,1 г лед ной уксусной кислоты и нагревают смесь при 170°С в течение 12ч.Example 1. A stainless steel autoclave (V 300 ml) was charged with 100 g of piperylene (trans: cis ratio 4: 56), 0.1 g of glacial acetic acid was added and the mixture was heated at 170 ° C for 12 hours.

Автоклав охлаждают и катализат перегон ют .The autoclave is cooled and the catalyzate is distilled.

Получено 68 г продуктов реакции, состо ших из 34,7 г (51%) целевого продукта (М. в. 10400) и 33,3 г (49%) щестичленных циклодимеров пиперилена.68 g of the reaction products were obtained, consisting of 34.7 g (51%) of the target product (M. v. 10,400) and 33.3 g (49%) of pesticylene cyclodimers.

Смесь последних (IV-VH) в основном содержит углеводороды IV-V (85%) (IV-VII), Т. кип. 84-85°С/47 мм рт. ст. 1,4720, ИК-спектр (v), CM-I: 720, 3030 (Ч«с-СН СН-), 980, 3030 (транс- -СН СН-), т/е 136. Полимер - совербесцветна  шенно прозрачна .The mixture of the latter (IV-VH) mainly contains IV-V hydrocarbons (85%) (IV-VII), T. kip. 84-85 ° C / 47 mm Hg. Art. 1.4720, IR spectrum (v), CM-I: 720, 3030 (H “s-CH CH-), 980, 3030 (trans-CH-CH-), t / e 136. The polymer is transparently transparent .

и в зка  масса с мол. весом 10400.and in a mass with a mol. weighing 10,400.

Пример 2. Нагревание 100 г транс-пиперилена , содержащего 5% г ыс-изомера при 150°С в течение 7 ч (концентраци  катализатора 1%) приводит к образованию 24,4 г (селективность 87%) целевого продукта (М. в. 13400) и 3,6 г (13%) шестичленных циклодимеров пиперилена состава, аналогичного описанному в примере 1.Example 2. Heating 100 g of trans-piperylene containing 5% g of ys-isomer at 150 ° C for 7 hours (catalyst concentration 1%) results in the formation of 24.4 g (selectivity 87%) of the desired product (M. c. 13400) and 3.6 g (13%) of six-membered piperylene cyclodimers with a composition similar to that described in Example 1.

Результаты полимеризации пиперилена представлены в таблице.The results of the polymerization of piperylene are presented in the table.

Таким образом, за счет применени  доступного катализатора предлолсенный способ позвол ет упростить технологию процесса.Thus, through the use of an available catalyst, the pre-catalyst method simplifies the process technology.
