    • In a method for the production of hydrocarbon resins based upon pyrolysates through cationic polymerization of the pyrolyzate in the presence of Friedel-Crafts catalysts and solvents at temperatures between -40.degree. and +60.degree. C., tetralin and/or tetralin derivatives are pyrolysed at 660.degree.-710.degree. C., preferably at 675.degree.-690.degree. C., in the presence of 1-10 mol, preferably 3-7 mol, vaporous water per mole tetralin or tetralin derivative with a dwell time of 1-2 seconds; the pyrolyzate is distilled to free it of high boiling (tarry) portions; and the unsaturated compounds contained in the distillate are polymerized in known manner. Styrene formed during the pyrolysis is preferably removed through distillation before the polymerization. The hydrocarbon mixture regenerated with the separation of the resins formed through polymerization are hydrogenated to tetralin and/or tetralin derivatives and again pyrolyzed.
    • 在-40〜+ 60℃的温度下,在Friedel-Crafts催化剂和溶剂存在下通过热解物的阳离子聚合制备基于热解物的烃类树脂的方法,四氢化萘和/或四氢化萘衍生物在 660℃-710℃,优选675℃-690℃,在1-10摩尔,优选3-7摩尔蒸气水/摩尔四氢化萘或四氢化萘衍生物存在下,停留时间为1-2秒 ; 将热解物蒸馏以使其沸腾(焦油)部分释放; 馏出物中所含的不饱和化合物以已知的方式聚合。 在热解过程中形成的苯乙烯优选在聚合之前通过蒸馏除去。 通过聚合形成的树脂分离再生的烃混合物被氢化成四氢化萘和/或四氢化萘衍生物,并再次热解。

    • Process of preparing .beta.-isopropylnaphthalene substantially free of corresponding .alpha.-isomer, in yields amounting to 90% and more by a continuous two-stage process comprising (1) alkylating naphthalene with propylene at a temperature of about 150.degree.-280.degree. C. under a pressure of 5 to 30 atm in the presence of a phosphoric acid catalyst supported on a SiO.sub.2 carrier and using a mol ratio of 1/5 to 1/20 mol propylene to 1 mol naphthalene to isopropylate 45 to 65% of the naphthalene and form a mixture of .alpha.- and .beta.-isopropylnaphthalene and then without separating off the unreacted naphthalene, (2) heating the isomeric mixture from stage (1) in the presence of a phosphoric acid catalyst supported on SiO.sub.2, to a temperature of 180.degree.-280.degree. C. under an inert gas pressure of 5 to 30 atm until no further .beta.-isopropylnaphthalene is formed and recovering said .beta.-isopropylnaphthalene from the isomerization mixture.
    • 通过连续两步法制备基本上不含相应α-异构体的β-异丙基萘的方法,其收率为90%以上,其包括(1)在约150℃-280℃的温度下将萘与丙烯烷基化, 在负载在SiO 2载体上的磷酸催化剂存在下,使用5〜30atm的压力,使用1/5〜1/20摩尔丙烯与1摩尔萘的摩尔比,将45〜65%的萘异丙酯化,形成 α和β-异丙基萘的混合物,然后不分离出未反应的萘,(2)在负载在SiO 2上的磷酸催化剂存在下,将阶段(1)的异构体混合物加热至180-280℃ 在5至30atm的惰性气体压力下进行,直至不再形成β-异丙基萘,并从异构化混合物回收所述β-异丙基萘。
