Chlorophenols are prepared by thermally dehydrochlorinating a corresponding chlorocyclohexanone in the presence of a catalyst having the formula: ##STR1## wherein A is phosphorus or arsenic, R.sub.1 and R.sub.2, which are identical or different, are each hydrogen, an alkyl radical having from 1 to 12 carbon atoms, a phenyl radical or a radical --NR.sub.4 R.sub.5, in which R.sub.4 and R.sub.5, which are identical or different, are each H or an alkyl radical having from about 1 to 5 carbon atoms, R.sub.3 is an alkyl radical having from 1 to 12 carbon atoms, a phenyl radical or a radical --NR.sub.4 R.sub.5, in which R.sub.4 and R.sub.5 are as defined above, and n is equal to 0 or 1.
氯酚是通过在催化剂的存在下热解相应的氯代环己酮制备的,该催化剂的化学式为:##STR1## 其中A为磷或砷,R.sub.1和R.sub.2相同或不同,分别为氢、具有1至12个碳原子的烷基基团、苯基或基团--NR.sub.4 R.sub.5,其中R.sub.4和R.sub.5相同或不同,分别为H或具有约1至5个碳原子的烷基基团,R.sub.3为具有1至12个碳原子的烷基基团、苯基或基团--NR.sub.4 R.sub.5,其中R.sub.4和R.sub.5如上所定义,n等于0或1。
