CS217402B1 - Process for treating acidic resins - Google Patents

Abstract

The invention relates to a method for processing acid resins, which are waste products in the refining of oils, vaselines, parex paraffins, crude benzols, etc., with sulfuric acid and/or oleum into sulfuric acid and resin. The aim of the invention is to process acid resins with low technical and economic costs. The problem is solved in such a way that by adding a solvent, the acid resins are separated into a sulfuric acid phase and a resin phase, which are technically usable. It has been found that additives for the separation of acid resins must contain 50 to 60 parts of acid resin, 25 to 40 parts of phenolic tar, and 10 to 25 parts of water. Better separation is achieved when the acid resin is added to the mixture at normal temperature with brief intensive mixing. The sulfuric acid phase and the resin phase are formed in a relatively short time at a deposition temperature of 50°C to 90°C, preferably 65 to 75°C.

OBJECT OF THE INVENTION A process for the treatment of acidic resins for sulfuric acid and resin, characterized in that 50 to 60 parts of the acidic resins are added with vigorous stirring at normal temperature to 20 to 45 parts of the phenol ester, i.e. the extraction and distillation product. crude phenol of specific density at 20 ° C 1.1 to 1.25 g / cm 2 with a distillation range of 230 to 350 ° C solidification temperature of about 20 ° C, and mixed with 10 to 25 parts of water before or after the addition of acidic resins, the solvent and the acidic resin mixture are fed to a separator in which at a temperature of 50 to 90 ° C, preferably 65 to 75 ° C, the resins in the organic phase and the sulfuric acid in the water phase are separated and collected separately. 2. Process according to claim 1, characterized in that acidic resins of various kinds are added. 3. A process as claimed in claim 1, wherein water and acidic resin are added to the excess of phenol tar while stirring in any desired amount and time. 4. Process according to claim 1, characterized in that the phenolic tar is continuously mixed with water and the acidic resin is continuously metered in the second mixing zone and the sulfuric acid and resin phases are removed separately after the separation zone flow. Recognized by the invention on the basis of the results of an expert review by the Office of Invention and Patenting, Berlin, DD.
