    摘要: 2-benzyl-1-alkanol polyglycol ethers having the formula: ##STR1## in which R.sup.1 is a C.sub.6 to C.sub.22 alkyl group; R.sup.2 is a C.sub.2 -C.sub.6 alkylene group; and n is an integer from 1 to about 100.The products are produced by heating a mixture of a ratio of an alcohol having the formula:R.sup.1 --CH.sub.2 --CH.sub.2 OHwherein the symbol R.sup.1 has the same meaning as above with a ratio of from about 1 mole to about 10 moles, preferably 1 to 3 moles, of benzyl alcohol to a temperature of from about 180.degree. C. to 250.degree. C. in the presence of an alkali metal compound, and optionally a hydrogenation catalyst; separating the excess benzyl alcohol from the mixture and alkoxylating the alcohol thus obtained.The polyglycol ether are used as wetting agents, dispersants, emulsifiers and detergents.
