泰尔登(Taractan)化学名2—氯—9—(3—二甲胺基—亚丙基)硫杂蒽,有安定及抗忧郁作用。对神经紧张、精神不安、焦虑、失眠等有一定疗效,且副作用不大。目前我厂生产工艺系用邻—氨基苯甲酸经重氮、缩合、环合、加成得到2—氯—9—(3—二甲胺基丙基)—9—羟基硫杂蒽(简称三级醇)后再经脱水,即得泰尔登(为α体),收率18～20％。同时还得到无药效的β体异构物。但β体经硫酸转化后 The name of Taractan 2-chloro-9- (3-dimethylaminopropylidene) thianthrene has the functions of stability and anti-depressant. On nervous, uneasy, anxiety, insomnia, etc. have a certain effect, and the side effects are not. At present, our factory production process with o-amino benzoic acid by diazotization, condensation, cyclization, addition to give 2-chloro-9- (3-dimethylaminopropyl) -9-hydroxythiophene anthracene Grade alcohol) and then dehydrated, that is, Telford (α body), the yield of 18 to 20%. At the same time also get non-effective β-body isomers. However, β-body after the conversion of sulfuric acid
