    摘要： Process for preparing 3,3,3-trifluoropropene-1 by contacting and reacting at least one of 1,1,1,3-tetrachloropropane, 1,1,3-trichloropropene-1 and 3,3,3-trichloropropene-1 and HF, under autogenous pressure, at 140.degree.-250.degree. C., in the presence of at least a catalytic amount of an organic monoamine, a salt of the monoamine or an alkylene diamine, said monoamine and salt being of the formula R.sub.3 N.(R'X).sub.n wherein n is 0 or 1, X is an appropriate anion, each R and R' is selected independently from H, alkyl of 1-16 carbon atoms, cycloalkyl of 6-10 carbon atoms, aryl of 6-10 carbon atoms and alkylaryl of 6-10 carbon atoms, provided, however, when n is 0, no more than two of the R groups are H and when n is 1, no more than three of the R and R' groups are H, and provided, however, R.sub.3 N taken jointly is piperidine, pyrrolidine, indoline, isoindoline, pyridine, quinoline or isoquinoline, each optionally substituted with 1-3 methyl groups, said alkylene diamine being of the formula R".sub.2 N--CH.sub.2 --NR".sub.2 wherein m is 2-10 and each R" is selected independently from H, alkyl of 1-4 carbon atoms and phenyl, provided, however, when m is 2, each R" is selected independently from alkyl of 1-4 carbon atoms and phenyl.
