The olefin sulfonates can be prepared in a known manner by reacting SO, inlt olefins of the formula RCH-CHR ₁ , in which R is an alkyl radical and R _{1 is} an alkyl radical or a hydrogen atom and preferably a hydrogen atom. The sulfonation is carried out in principle in such a way that a stream of SO2, which is strongly diluted with an inert gas such as air, is allowed to act on the olefin, preferably an OC-olefin, a viscous acidic product which is assumed to be obtained that it contains alkene sulfonic acids and sultones.

During hydrolysis and neutralization, for example by treatment with strong aqueous alkali, sultones contained in the product are converted into the corresponding oxyalkanesulfonic acids. The product containing long-chain alkenylsulphonic acids and oxyalkanesulphonic acids can then be extracted ("de-oiled") to remove water-insoluble inactive substances such as suItones in order to improve the detergency of the mixture treat the sulfonation product with strong sulfuric acid® before neutralizing. The product obtained in this sulfuric acid treatment, which is preferred for the detergents according to the invention, contains significantly larger amounts of alkenyl sulfonate and only small amounts (for example less than 1/3 or 1/3 total sulfonate or even less) or none at all

The starting material for the sulfonation can, for example, contain monoolefins with 8 = 25 carbon atoms / preferably those with 12-21 carbon atoms. In addition, the starting material can also contain small amounts of other constituents such as secondary or internal olefins, diolefins, cyclic olefins. ^ Contain aromatics, naphthenes and alkanes and can be hardened by cracking petroleum wax, catalytic polymerization of ethim , dehydration of long-chain alcohols and the like. The best results have so far been achieved when the starting material consists for the most part, for example more than 70% and preferably at least 90%, of oC-olefins (in at least 90%). A particularly preferred starting material contains about 12 to 21 carbon atoms in the molecule and gives alkenyl sulfonates with excellent washing properties. Particularly good foaming and cleaning properties were achieved when the starting materials were mixed, the oC-olefin content of which consisted essentially of compounds with 15 to 18 carbon atoms.

The sulfonation is preferably carried out with a molar ratio (volume) of inert gas to SQ in the range from 5 μl to 100 μl and preferably at least about 10: 1, for example 50 μl to 20 μl.

Suitable inert gases for diluting the sulfur trioxide are for example air and nitrogen, which are preferred, and furthermore carbon dioxide, sulfur dioxide, low molecular weight Paraffinic hydrocarbons and the like. Da® gaseous sulfur oxide can either be obtained by evaporation of stabilized liquid sulfur trioxide can be obtained or as a converter gas from a sulfur burner.

When performing the first implementation between SO, and It is advantageous to have intimate contact between olefins the gaseous SO, and the olefin must be observed. This can expediently and in a continuous manner that the SO, is allowed to act on one or both surfaces of a thin flowing film of the olefin starting material, for example by putting a thin flap over the Inner wall of a pipe can flow down, in the middle of which one SO, initiates.

In general, it is advisable to keep the temperature as low as possible, eg a temperature that 3 ° G or less above the temperature at which solidification or precipitation occurs. Since the reaction between SO- * and olefins is exothermic, it is advisable to work with cooling!

The sulfuric acid treatment is preferably carried out at a temperature at which the mixture remains in a flowable state. This Teiaperatur is for example in the range from about IO to 10O ⁰ C and preferably in the range of about 25 to 60 ° C. The duration of the sulfuric acid treatment is relatively short and is preferably less than about an hour, with the best treatments with treatment times of less than 1 hour. 20 minutes, for example 5 minutes or less, can be achieved. Even good results were obtained if the sulfuric acid was introduced into the mixture from stage I less than 1 minute before the mixture was treated with an alkaline neutralizing agent (e.g. excess aqueous NaOH). In one experiment, the mixture from stage I was mixed with sulfuric acid .d raised to 55 ° C for about 15 seconds and then immediately neutralized.

The sulfuric acid can be added in any suitable device, preferably in one in which the Components are mixed together quickly and thoroughly.
