Liquid 1,1-dichloro-1-fluoroethane containing contaminating unsaturated carbon compounds is treated with chlorine and ultraviolet light to convert the unsaturated contaminants to photochlorination products. The photochlorination products are thereafter separated from 1,1-dichloro-1-fluoroethane, such as by distillation. The process is particularly useful in separating vinylidene chloride from 1,1-dichloro-1-fluoroethane. |

| 145 | Stabilised chloroparaffins | EP86307581.8 | 1986-10-01 | EP0222489A1 | 1987-05-20 | Bieding, Robert; Nestler, Heinz |
The invention concerns the stabilisation of chloroparaffins to produce stabilised chloroparaffins which are suitable for use as solvents in self-copy papers in which they no longer lead to discolouration of the leuco-base or to appreciable fogging in the paper. The stabilised chloroparaffins contain magnesium alcoholates in quantities between 0.05 and 2.0% by weight based on the chloroparaffin. The magnesium alcoholates can be derived from aliphatic alkanols or from ether alcohols; the preferred stabiliser is magnesium methylglycolate. |

A nitrogen halide or carbon halide gas is caused to pass through a packed layer in which at least one granular material selected from the group consisting of silicon, molybdenum, tungsten, molybdenum silicide, and tungsten silicide is heated, so that the halide gas and granular material react with each other. The reaction product is treated with an alkali. In this manner, a toxic halide gas can be detoxicated with high efficiency. |
