Synol procedure

The Synol process is a technical process for the production of primary alcohols from synthesis gas . The process was carried out from around 1940 as a modification of the Fischer-Tropsch synthesis .

Procedure

For the preparation of the product mixture so-called Synol is, synthesis gas at a pressure of 18 to 25 bar and temperatures of 190 to 200 ° C over a having about 2.5% alumina and 0.5% potassium oxide offset iron oxide catalyst passed.

The product obtained is a mixture of primary alcohols of different carbon chain lengths, starting with ethanol (C ₂ ) up to about C ₂₀ , which represent about 30 to 70% of the yield depending on the reaction conditions. In addition, esters , fatty acids and aliphatic and olefinic hydrocarbons are obtained.

The resulting products are separated by distillation, some after esterification with boric acid .
