Abstract

Synthesis of petroleum resins in the presence of aliphatic N-substituted aminoperoxides of general formula C(CH3)3–O–O–CH2–N–R1R2 was investigated in this communication. The effects of reaction temperature (393–493 K), reaction time (240–480 min) and aminoperoxide concentration (0.032–0.096 mol/l) on the yield and characteristics of the petroleum resins were studied. The correlation index (0.85–0.92, absolute value) for the pair "yield–bromine number" confirmed that the oligomerization reaction proceeded on monomer's unsaturated bonds. It was found that the obtained resins were mainly styrene-cyclopentadiene cooligomers. Depending on the initiator used, they contained 38.8–40.41% styrene and 31.1–33.04% cyclopentadiene. The analysis of the experimental results demonstrated that the most significant effect (correlation index of 0.75–0.88) on the yield of petroleum resins had the reaction temperature. Compared with thermal oligomerization (without initiator), the use of aminoperoxides allowed increasing the product yield (453 K, 360 min, 0.064 mol/l) by 4.6–18.3%. The yield of petroleum resins did not correlate with the reaction time. Blending the obtained resins with petroleum bitumen increased the composition stability in aggressive environments.

在脂肪族氨基过氧化物存在下合成石油树脂

研究了在通式C(CH3) 3-O-O-CH2-N-R1R2的脂肪族n -取代氨基过氧化物存在下石油树脂的合成。研究了反应温度(393 ~ 493 K)、反应时间(240 ~ 480 min)和氨基过氧化物浓度(0.032 ~ 0.096 mol/l)对石油树脂收率和性能的影响。“产率-溴数”对的相关指数(0.85 ~ 0.92，绝对值)证实了低聚反应是在单体的不饱和键上进行的。结果表明，合成的树脂主要为苯乙烯-环戊二烯冷聚物。根据引发剂的不同，它们含有38.8-40.41%的苯乙烯和31.1-33.04%的环戊二烯。实验结果分析表明，反应温度对石油树脂收率的影响最为显著(相关指数为0.75 ~ 0.88)。与热聚反应(无引发剂)相比，氨基过氧化物的使用使产物收率(453 K, 360 min, 0.064 mol/l)提高了4.6-18.3%。石油树脂得率与反应时间无关。将得到的树脂与石油沥青混合，提高了其成分在腐蚀性环境中的稳定性。

期刊介绍： Voprosy Khimii i Khimicheskoi Tekhnologii (Issues of Chemistry and Chemical Technology) is published bimonthly by the Ukrainian State University of Chemical Technology and accepts Ukrainian- or English language high-quality original articles and reviews concerning various fields of research in chemistry and chemical engineering. Our unusual title “Voprosy khimii i khimicheskoi tekhnologii” originates from the transliterated initial Russian title “Issues of Chemistry and Chemical Technology“. The fact of the matter is that Voprosy khimii i khimicheskoi tekhnologii was founded in 1965 as a scientific journal mainly for Russian-reading and Russian-speaking readership when «the Iron Curtain» existed. Since 1991, after Ukraine declared its independence, our Journal began to publish the articles in Ukrainian and English. Multilingualism is our established tradition. We remember and cherish our traditions, but we follow the latest trends in modern science. Papers that are multidisciplinary or address new or emerging areas of chemistry and chemical engineering are particularly encouraged. Thus, the scope is dynamic. It includes but is not limited to the traditional areas of general, inorganic, organic, analytical, physical chemistry and electrochemistry, as well as all conventional areas of chemical engineering (chemistry of high molecular compounds, technology of inorganic and organic substances, processing of combustible minerals, chemical technology of silicates, processes and apparatus of chemical productions, etc.). The Journal publishes papers dealing with newer interdisciplinary areas such as materials science, nano-science, catalysis, computational and theoretical chemistry, surface phenomenon and colloidal systems, environmental chemistry, green chemistry.
