Abstract
A method of making alcohols involves forming of alcohol esters from liquid alkane halides and a solution of metallic salts of organic acids to produce gaseous alcohol esters for reaction with magnesium or metal hydroxides to form the alcohol and the metal salt of the organic acids. In an improvement method liquid phase alcohol esters instead of gaseous alcohol esters are produced from liquid alkane halides and a solution of metal salts of organic acids whose alkane esters are less soluble in water than that of the alkane halide and treating of the alcohol ester formed with magnesium or metal hydroxides to form the alcohol and the metal salt of the organic acids.
Claims10
A method for the production of alcohols comprising:
- contacting an alkane gas with an aqueous halide saturated solution to strip the halide from the solution to form a mixture of an alkane and a halogen gas;
- reacting the halogen gas with the alkane to form an alkyl halide, an alkyl di halide, an alkyl tri halide, and a hydrogen halide gasses;
- neutralizing the alkyl di halide, the alkyl tri halide, and the hydrogen halide gasses but not the alkyl halide gas with a suspension of magnesium hydroxide;
- cooling the gasses from the neutralizing step to a temperature to liquefy at least a portion of the gasses to form liquefied gasses;
- reacting the liquefied gasses with a metal salt of an organic acid to form an alkyl ester, wherein the alkyl ester is water insoluble and the reaction produces an ester insoluble layer comprising the alkyl ester and a water layer comprising water and magnesium halide;
- and
- contacting the ester insoluble layer with a suspension of magnesium hydroxide to form an alcohol from the alkyl ester.
A method for the production of alcohols comprising:
- contacting ethane gas with an aqueous solution saturated with bromine to strip the bromine from the solution to form a product mixture of the ethane and the bromine;
- reacting at 350° C. to 450° C. the ethane and the bromine to form an ethyl bromide, an ethyl dibromide, an ethyl tribromide, and a hydrogen bromide gasses;
- neutralizing the ethyl dibromide, the ethyl tribromide, and the hydrogen bromide gasses but not the ethyl bromide gas with a suspension of magnesium hydroxide;
- cooling the gasses from the neutralizing step to a temperature to liquefy at least a portion of the gasses to form liquefied gasses;
- reacting the liquefied gasses with an aqueous solution of magnesium benzoate, a magnesium butyrate, or both to form a ethyl benzoate, a ethyl butyrate, or both, wherein the ethyl benzoate and the ethyl butyrate are water insoluble and the reaction produces an ester insoluble layer comprising the ethyl benzoate, the ethyl butyrate, or both and a water layer comprising water and magnesium bromide;
- and
- contacting the ester insoluble layer with a suspension of magnesium hydroxide to form ethanol.
