This is extracted with alcohol and the residue briquetted and treated in much the same manner as in the Meunier patents. Br. 12207/n. Meunier, G. App. May 20, 1911; Acc. May 20, 1912. Br. 13018/11.

In order to extract glycerine, succinic acid, and other useful products from vinasse, the latter is mixed with cellulose (preferably wood cellulose) which has been completely or partially carbonized with sulphuric acid, and the mixture is dried and extracted with suitable solvents, such as crude alcohol, aided by pressure or osmosis if necessary. The residue left after extraction may be molded into briquets and burnt, whereby alkaline salts or crude pearl ash is obtained; or, it may be subjected to dry distillation to obtain methyl alcohol, acetic acid, and other products. The coke from the distillation contains oxalic acid and cyanides, and after extraction of these by lixiviation, the residue may be used as a fuel or converted into a filtering material. The crude glycerine may be purified by further treatment with carbonized cellulose. Ger. 253573. Guignard and Watrigant. Pat. May 27, 1911; Pub. Nov. 12, 1912. Br. 12737/11. Guignard and Watrigant.
