Дозировка Озоннна-97 (1,268 вес.ч.) выбрана на основе предварительных испытаний и сравнени его эффективности с эффективностью других производных 3(5)-метилпиразола. Дозировка Диака-3 и бифургина, рекомендуема дл применени в промышленных издели х , - 4 вес.ч. на 100 вес.ч. каучука . Дл испытани предлагаемого вулканизующего агента приготовл ют смеси на лабораторных вальцах следующего состава, вес.ч: каучук СКФ-26 100; окись магни 15,0; фторид кальци 35,0; вулканизующий аге.нт - дозировка указана выше. Смеси вулканизуют в две стадии : первую провод т в прессе при 150с в течение 30 мин, вторую - в термостате на воздухе при в течение 24 ч. Старение вулканизатов провод т на воздухе при в течение 3; 5 и 10 суток. Результаты испытаний представлены в таблице.pa formalin and 40 ml of isopropyl alcohol. With stirring, a solution of 41.7 g (0.5 mol) of 3 (5) -methylpyraol in 50 ml of isopropanol is added to the thick white mass that is formed. The ray mixture is heated to boiling, the reaction mass goes into solution and the latter is boiled for 5 hours. After the end of the reaction, solvent is distilled off from the reaction mixture, and then 250 ml of cyclohexane is added to it at boiling. The solution obtained is fil hot. After cooling, a white crystalline precipitate, O.Zonin-97, falls out of the filtrate. . Get 27 (49.3%) of the target product, so pl. 96, 97 ,. Found,% t C 61.46; H 7.68; N 30.68. C, 4H5JH, .. .. Calculated,% t С o1.80; H 7.36; N 30.87. The test of Ozonin-97 as a vulcanizing agent for rubber compounds based on fluororubber SKF-26 was carried out in comparison with bifurgin, used in domestic industry, and Diac 3, which is used in industry abroad. The dosage of Ozonnna-97 (1.268 parts by weight) was selected on the basis of preliminary tests and a comparison of its effectiveness with the effectiveness of other 3 (5) -methyl pyrazole derivatives. The dosage of Diak-3 and bifurgin, recommended for use in industrial products, is 4 parts by weight. per 100 weight parts rubber For testing the proposed vulcanizing agent, mixtures are prepared on laboratory rolls of the following composition, parts by weight: SCF-26 rubber 100; magnesium oxide 15.0; calcium fluoride 35.0; vulcanizing agent. dosing is indicated above. The mixtures are vulcanized in two stages: the first is carried out in a press at 150 s for 30 minutes, the second in a thermostat in air for 24 hours. The aging of vulcanizates is carried out in air for 3; 5 and 10 days. The test results are presented in the table.

Из данных таблицы видно, что Озонин-97 вл етс эффективным вулканизующим агентом фторкаучука СКФ-26. Он сообщает вулканизатам высокие физико-механические свойства после термостарени . По теплостойкости вулканизаты с Озонином-97 несколько превосход т вулканизаты с бифурпином и примерно равноценны вулканнзатам с Диаком-3.From the data in the table it can be seen that Ozonin-97 is an effective vulcanizing agent for the fluororubber GFR-26. It informs the vulcanizates of high physical and mechanical properties after thermal aging. In terms of heat resistance, vulcanizates with Ozonin-97 are somewhat superior to those of bifurpin and are approximately equivalent to those of Diac-3.
Кроме того, предлагаемый вулканизующий агент не вызывает подвулканизации резиновых смесей. Преимуществом Озонина-97 вл етс также значительно меньша дозировка его в смеси по сравнению с вулканизующими агентами , примен емыми в промышленности.In addition, the proposed vulcanizing agent does not cause vulcanisation of rubber compounds. The advantage of Ozonin-97 is also a considerably lower dosage of it in the mixture as compared with vulcanizing agents used in industry.
