Zinc chloride finds numerous applications in various industries, and its scope will increase through research, with the course of time. Anhydrous zinc chloride is synthesized by treating zinc with hydrogen chloride. Zinc alkyl esters interact with the organotin compound to prevent PVC degradation but surprisingly do not form zinc chloride, a known PVC destabilizer, provided the equivalents of zinc do not exceed the active equivalents of non-alkyl mercapto or carboxylate components in the organotin stabilizer. The yield of pure hydrocarbon after a single crystallization was 64% of that calculated based on the aluminum chloride used. The xylose yield was > 90% (w/w) at 70{degrees}C.
