Isothiocyanic acid-1-naphthyl ester (CAS NO.551-06-4) is used as analytical reagents and organic synthesis intermediates.
From α-naphthyl thiourea in chlorobenzene was heated to return the system. The α-naphthyl-thiourea join the chlorobenzene, the heating return dissolved and continue to return to 8h. Chlorobenzene recovery after decompression, cooling crystallization, with n-hexane extraction, recovery of n-hexane, were crude, acetone recrystallization that was finished, the yield of 85%.
