Abstract
The reaction of ethylene with nitrogentetroxide, below the critical temperature of the latter, to produce 1 : 2-dinitroethane, b -nitroethanol and b -nitroethylnitrate is effected in the presence of oxygen. In an example, a mixture of dry ethylene and oxygen is passed into liquid nitrogen tetroxide. The resulting mixture, is degassed by passing in air and is poured into methanol cooled with solid carbondioxide and methanol. 1 : 2-Dinitroethanol, thus precipitated is separated and the methanol removed from the remaining solution. The resulting oil is treated with a mixture of benzene and water to separate the b -nitroethanol from the b -nitroethylnitrate. The latter is obtained from the benzene solution, and the aqueous solution is neutralised and extracted with ether to obtain the b -nitroethanol. A mixture of oxygen with an inert gas, such as air may be employed instead of oxygen. Specification 575,618 is referred to.
