  The company known as: Böhme Fettchemie-Gesellschaft mit beschränkter Haftung in Chemnitz, Saxony (Germany). Process for the production of surface activity sulfonation products. International Convention: German patent application filed on September 20, 1943.



   It has been found that surface active sulfonation products can be obtained when hydropyranalkanols are treated together with carboxylic acids or their functional derivatives or with combinations containing hydroxyl radicals, with sulfonating agents which optionally contain additions. capable of fixing water and that the reaction products are neutralized with inorganic or organic bases. Instead, the hydropyranalkanols can also be reacted first with carboxylic acids or their functional derivatives or alternatively with combinations containing hydroxyl groups and then treated the intermediates formed with sulfonating agents.



   The hydropyranalkanols serving as raw material can, for example, be obtained by cyclization of derivatives of 1,5-dlol or of diols with hydroxyl groups even further apart from each other which additionally contain a third hydroxyl group or a reaction radical exchangeable against a hydroxyl, or from

  Neutralization could also be carried out using ammonia or organic bases.



   Depending on the choice of raw materials, the products are more or less soluble in water. Their aqueous solutions exhibit properties with superficial activity. Therefore, the products can serve as wetting agents, detergents, dispersing agents, washing agents, and for other similar purposes.

  1. A method of manufacturing sulfonation products with surface activity, characterized in that hydropyranaloanols are woven together with carboxylic acids or their functional derivatives or alternatively with combinations containing hydroxyl radicals, by agents which optionally contain additions capable of fixing water, and which neutralizes the reaction products with inorganic or organic bases.
