| Abstract | OF THE DISCLOSURE Linear 3-alken-1-ols of from 11 to 15 carbon atoms are formed by reacting formaldehyde and a linear olefin. Compounds exhibiting desirable detergent properties re sult from sulfation, ethoxylation, ethoxylation and sulfa tion, or ethoxylation and dihydroxylation of the 3-alken 1-ols. CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation-in-part of our appli cation Ser. No. 687,137, filed Dec. 1, 1967 and now abandoned, which was in turn a continuation-in-part of our application Ser. No. 618,824, filed Feb. 27, 1967 (now U.S. Pat. 3,544,603). This application is related to the subject matter of our applications Ser. Nos. 84,161 and 84,226, each filed Oct. 26, 1970, as continuations-in-part of said application Ser. No. 618,824, and to our concur rently filed application for 1,3,4-Triols and Derivatives Thereof (Ser. No. 135,427, filed Apr. 19, 1971). BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for synthetic alcohols. These alcohols have a variety of uses, and are especially useful for conversion to deter gents. Nonionic detergents, formed by the ethoxylation of linear alcohols, have been very popular in recent years. The growth in the use of nonionics has been due in part to special properties such as whiteness, liquid state, in creasing activity with temperature and effectiveness with out the requirement for the presence of builders. A disadvantage in using higher alcohols for various purposes, including preparation of detergents, has been the high cost of the alcohols. With the recent availability of alpha olefins in the detergent range, there have been many efforts to find suitable low cost ways of making detergents directly from the alpha olefins. There are sev eral theoretical methods for doing this, among which can be included oxidation with ozone in order to form the carboxy acid with one less carbon atom than the olefin; sulfation, which gives only the secondary alcohols; high pressure synthesis with carbon monoxide and the oxo reaction to give a primary alcohol and the abnormal reverse addition of hydrogen bromide to the alpha olefin to form a primary bromide which can be hydrolyzed to the primary alcohol. The two most commercially feasible methods appear to be the oxo reaction and the hydrogen bromide reverse addition. The first is marked by the high cost of the high pressure reaction that must be carried out with the carbon monoxide and the second by the diffi O |
