• Another object of the invention is the development of a process for obtaining the above polyalkylene glycol ethers of B-hydroxymercaptans by alkoxylation.
• novel polyalkylene glycol ethers of B-hydroxymercaptans are non-ionic surface active compounds which are utilizable as wetting agents, emulsifying agents or detergent substances, depending on the chain length of the alkyl residue present in the initial mercaptan and the number of alkylene oxide groups added on.

• the present invention therefore provides a process for the production of sulfur-containing alkylene oxide adducts with improved surface-active properties comprising reacting a mercaptan having from 6 to 24 carbon atoms, which carries a hydroxyl group on the carbon atom adjacent to the SH group, with an alkylene oxide having 2 to 4 carbon atoms, in the molar ratio 1:1 to 1:50.
• Suitable starting substances are aliphatic and cycloaliphatic B-hydroxymercaptans, especially aliphatic fl-hydroxyalkylmercaptans with terminal mercapto groups.
• alkyl chains of these aliphatic B-hydroxyalkylmercaptans may contain double bonds, be branched or substituted or interrupted by cycloaliphatic and/or aromatic groups.
• the alkyl chains may also be substituted and/or interrupted by hetero atoms or hereto atom groups, which do not interefere with the alkoxylation reaction, for example halogen atoms or ether groups.

• B-Hydroxymercaptans are formed when the epoxide ring is opened by means of hydrogen sulfide or metal hydrogen sulfides, fi-hydroxyalkylmercaptans with relatively long chains, such as are used as starting substances in the process according to the invention, may be prepared in good yields, for example, by the process according to the copending US. patent application Ser. Nos. 818,390, naw abandoned and 818,444, both filed Apr. 22, 1969, by reacting corresponding epoxides with hydrogen sulfide in the presence of catalytic amounts of bases.
• alkylene oxides with 2 to 4 carbon atoms to be added on to the fi-hydroxymercaptans are, for example, ethylene oxide, propylene oxide, butylene oxide-1,2.
• Substituted alkylene oxides such as glycide or epichlorhydrin may also be used.
• the alkylene oxides may be added on to the B-hydroxyalkyl mercaptans separately, in admixture with one another or successively in any sequence. Such mixed adducts also display foam-regulating effects in addition to surfaceactive properties.
• the amount of the alkylene oxide to be added on depends partly on the number of carbon atoms in the hydroxyalkylmercaptan to be used and partly on the particular purpose for which the surface-active substances prepared are to be used. In general, in order to obtain good surface-active properties, the amount of alkylene oxide to be added should be greater, the larger the number of carbon atoms in the fl-hydroxyalkylmercaptan. n the other hand, for the preparation of a substance utilizable as a wetting agent from a particular fi-hydroxyalkylmercaptan, a smaller amount of alkylene oxide should be added on than in the case when the product is to be used as a cleaning agent.

From the chemical standpoint, the products are mixtures in which, besides such alkylene oxide adducts in which only the mercapto group participated in the reaction, fi-hydroxyalkylmercaptans alkoxylated both on the mercapto group and secondary hydroxyl group are present. Separation of the components of the mixture is not generally necessary for the applications described above.
