| titleOfInvention | METHOD FOR PRODUCING TEAR AND SULFUR ACID ARISM DIALKYLBENZOLE SULPHONESEES FROM THE BODENAL CYLATE OF THE SYNTHESIS OF LINEAR ALKYL BENZENES |
| abstract | Process for the preparation of dialkylbenzenesulphonic acids which are low in tar and sulphuric acid from the bottom alkylate of the synthesis of linear alkylbenzenes, in which process a) a bottom alkylate in the form of the distillation residue of the synthesis of linear alkylbenzenes from chlorinated paraffin and benzene is fractionated using an aluminium chloride catalyst in such a manner that a fraction is obtained whose boiling range is from approximately 400 to 435@C and which contains not more than 16% by weight of diphenylalkanes, b) this fraction is sulphonated using gaseous sulphur trioxide, c) most of the tar and sulphuric acid is removed from the sulphonation mixture by a precipitation with mineral oil or synthetic oils or a mixture of these, and d) the remaining sulphuric acid is precipitated as calcium sulphate using inorganic calcium compounds in the presence of small amounts of water. |
