Abstract: 2-Perfluoroalkyl ethanols are obtained by reacting 2-perfluoroalkyl ethyliodides with at least the two-fold molar amount of nitric acid of about 70 to 98 percent strength and hydrogenating the intermediates, which are the nitrates of the desired ethanols. The products are useful as starting materials for the production of hydrophobic and oleophobic textile finishing agents, e.g. the polymer acrylates and methacrylates of said 2perfluoroalkyl-ethanols.

Abstract: Flowable pasty raw materials for detergents capable of being pumped and having a content of washing active substance of more than 60% are obtained by neutralizing organic sulfuric acid semiesters or sulfonic acids with alkalies. Before neutralization the sulfuric acid semi-esters or sulfonic acids are degassed and neutralization is carried out in a continuous flow mixer. The greater proportion of the mixture is conducted in a cycle whereas a smaller proportion is withdrawn as finished product. In the continuous flow mixer the usual buffer substances and preserving agents may be added to the products.
