Inorganic zinc means a zinc compound which does not contain a hydrocarbon element (generally, more generally contains an alkyl group), such as zinc oxide, zinc chloride and zinc nitrate, and the like is in the range of inorganic zinc. The organic zinc must contain hydrocarbons in the molecular formula, such as zinc isooctanoate, zinc naphthenate, dimethyl zinc, and dibutyl zinc laurate, which belong to the class of organozinc. From the physical appearance, most of the inorganic zinc is white solid crystal, and part of the organic zinc is a part of the liquid which is solid. Inorganic zinc mostly uses its physical properties as a filler, and organozinc is used as a catalytic phase for proton transfer for the acceleration of compounding reactions and most of the pharmaceutical fields.
Compared with antimony and tin, organozinc catalysts have slower reaction rates; very effective cross-linking catalysts, the final product surface is not sticky, and can be used for adhesives, elastomers, slurries, soft foams.
