Abstract
Covalent isocyanates of the formula M(NCO)n are prepared by refluxing a mixture of sodium cyanate or potassium cyanate with a covalent halide of formula MCln or MFn in an inert polar solvent or reaction medium, or in a mixture of an inert polar solvent or reaction medium with an inert non-polar solvent, subsequently separating precipitated sodium or potassium halide and fractionally distilling the liquid phase to remove solvent or medium. In the above formula M represents either one of the elements aluminium, lead, arsenic, antimony, vanadium, or iron, or one of the groups vanadyl, sulphuryl, thionyl and chromyl; and n represents the covalency of the element or group. When a mixed solvent is used, the polar solvent preferably constitutes 10-20% by weight of the whole solvent. Suitable non-polar solvents are benzene, paraffins, chlorohydrocarbons and ethers, while suitable polar solvents are nitriles (e.g. acetonitrile), ketones (e.g. acetone), esters (e.g. ethyl acetate), nitroparaffins and liquid sulphur dioxide. Specificatio 907,029 is referred to.
