New Disinfectant / Fumigants for Silkworm Rearing and Egg Production

摘要

A number of new disinfectants, ncluding chlorine dioxide, have become popular, and replaced formalin in silkworm rearing. Recently, an environment-friendly disinfectant in oxidized form with universal bactericidal spectra has been reported by Chinese workers. 1 ,3-Dibromo-5,5-Dimethyl-hydantoin, more commonly known as Dibromodimethyl hydantoin or DBDMH, is a cheap and convenient alternative to NBS (N. bromosuccinimide). A mild and efficient oxidation of various thiols affords the corresponding disulfides using 1,3-dibromo-5,5-dimethyl-hydantoin (DBDMH) as oxidant under both solution and solvent-free conditions (A. Khazaei ef al. 2004, Synthesis, 2959). The synonyms are, Dibromantin, Take Charge Orange etc.
