Judging from your workup it is also unlikely that the liquid you got is allyl mercaptan since its bp is 67-68°C. You would have to distill the CH2Cl2
extract through an efficient column to separate allyl mercaptan from CH2Cl2. It is more likely that what you obtained is mainly diallyl disulfide (bp
180-195°C). Mercaptans easily oxidize to disulfides unless all solvents used are deareated and if its solutions are left exposed to air for too long.
