| titleOfInvention | PROCESS FOR SULFONIZING HYDROCARBONS WITH GASEOUS SULFUR TRIOXIDE TO A DESIRED DEGREE OF SULFONATION |
| abstract | Hydrocarbons are sulphonated to a desired degree between 80-99.5% by gaseous SO3. During sulphonation, a constant partial stream is continuously removed from the mixt. for degassing and adjusting to a temp. where the density is measured. The alteration is density w.r.t. time is employed to indicate the progress of sulphonation, after making an adjustment for the time lost in removing the partial stream and measuring the density. Extrapolation is used so sulphonation is stopped when the desired density is reached. The density is pref. measured at a temp. held constant to within plus or minus 0.02 degrees C. Used e.g. for the sulphonation of fatty alcohols, olefins, and alkyl benzenes in mfg. raw materials for washing agents. The process is largely automatic and can be undertaken without the need of specially trained analysts. The desired degree of sulphonation can be achieved with an accuracy unobtainable by conventional processes. |
