High purity monoalkyltin compounds and uses thereof

The present invention relates to high purity monoalkyltin compounds, more specifically to alkyltin compound compositions containing monoalkyltin as major compound, and minor quantities of di- and/or trialkyltin compounds. The present invention also relates to the preparation processes of such high purity monoalkyltin compounds, as well as to the uses of said monoalkyltin compounds as chlorine-containing polymer-stabilisers, glass coating chemicals and catalysts, as well as articles comprising at least one polymer matrix and a high purity monoalkyltin compound.

Process for the preparation of mono- and dialkyltin halogen compounds and use thereof

Production of mixtures of monoalkyl tin trichlorides (I) and dialkyl tin dichlorides (II) by reacting tin tetrachloride with an alkyl aluminum compound in the form of an ether donor complex comprises using an amount of ether in excess of that required to form the complex. Independent claims are also included for: (1) mixtures of (I) and (II) produced as above in a yield of at least 90 mole% based on tin tetrachloride; (2) mixtures of (I) and (II) comprising at least 50 mole% (I); (3) mixtures of (I) and (II) comprising up to 5 mole% trialkyl tin chlorides; (4) mixtures of (I) and (II) comprising at least 50 mole% (I), at least 20 mole% (II) and up to 5 mole% trialkyl tin chloride.

Method for producing monoalkyl-tin-trihalides

Monoalkyl-tin-trihalides are prepared in a high yield by a method in which a stannous halide reacts with an alkyl halide in an organic solvent in the presence of a catalytic substance selected from the group consisting of magnesium, iodine, bromine, Grignard reagents and a mixture of two or more of the above-mentioned substances, the organic material being selected from liquid alcohols, tetrahydrofuran, liquid organic acids, liquid esters of organic acids, liquid ketones, liquid hydrocarbons and mixtures of two or more of the above-mentioned compounds, and the resultant monoalkyl-tin-trihalide is isolated from the reaction mixture.
