Documented Uses

• A degradation product of dibutyltin and tributyltin (antifouling agents in marine paints); Used as an intermediate for other mono-n-butyltin compounds, a PVC stabilizer, and a hot-end coating of glass bottles; [HSDB]
• Glass Manufacturing [Category: Industry]
• Hot-end coating of glass to improve abrasion resistance and bursting strength of glass bottles.
• Although generally less effective than dialkyl tin compounds as PVC stabilizers, monoalkyltin compounds when added to dialkyltin compounds in amounts of 5-20 wt% exert a synergistic effect on stabilizer effectiveness, preventing early yellowing.
• REDISTRIBUTION REACTION OF TETRA-N-BUTYLTIN & STANNIC CHLORIDE IN AN APPROX 1:3 RATIO TO FORM A MIXTURE OF CHLOROBUTYLTINS, FOLLOWED BY SEPN; OXIDATIVE ADDITION OF N-BUTYL CHLORIDE TO STANNOUS CHLORIDE IN THE PRESENCE OF TRI-N-BUTYLANTIMONY CATALYST.
• The oxidative addition of aliphatic organic halides to stannous chloride has long been of interest for the preparation of monoorganotin trihalides. Fair to good yields are obtained for the reaction with quaternary ammonium or phosphonium catalysts. Trialkylantimony compounds at 100-160 °C are also used as catalyst.
