Abstract
A process for ortho-para-hydrogen conversion characterized by the use as a catalyst of a sulphur-containing semiconductive polymer produced by the dehalogenation of a poly(tetrahalophenylene sulphide) in the presence or absence of an organic solvent at 150.degree.-500.degree. C.
Claims8
In a process for the ortho-para conversion of hydrogen wherein hydrogen is contacted with a catalyst at the desired conversion temperature, the improvement which comprises said catalyst being a sulphur-containing semiconductive polymer produced by dehalogenating a poly(tetrahalophenylene sulphide) in the presence or absence of an organic solvent at a temperature from 150.degree. to 500.degree. C.
