Abstract

1,188,673. Phenylthioureas. PERNIX ENTHONE. 10 March, 1967 [14 March, 1966], No. 11330/67. Heading C2C. [Also in Division C7] Monophenylthiourea is produced by evaporating an aqueous solution of aniline hydrochloride and ammonium thiocyanate and heating the residue. N,N<SP>1</SP>-diphenylthiourea is made by heating a mixture of aniline, carbon disulphide and a lower alkanol in the presence of sulphur. Other unsubstituted and substituted mono- and di-phenyl thioureas are referred to, with a formula
