NOVEL ALKOXYLATE-CONTAINING COMPOSITIONS
-
Page/Page column 9-10, (2008/12/08)
Compositions comprising novel alkylene oxide-extended alkoxylates of a linear or branched 1,3-dialkyloxy-2-propanol are disclosed. In these compositions the alkoxylates may offer a variety of desirable properties, including but not limited to service in formulations as surfactants, detergents, wetting agents, defoam/low foam agents, stabilizers, and the like. The compositions may include products such as detergents, pharmaceuticals, paints and coatings, plastics, oilfield chemicals, agricultural agents, and the like.
NOVEL BRANCHED ALKOXYLATES

Page/Page column 9-10, (2008/12/08)
Novel alkylene oxide-extended alkoxylates of a branched 1,3-dialkyl-oxy- 2-propanol may be prepared by a convenient process comprising adding epichlorohydrin to a stoichiometric excess of a branched alcohol, wherein the molar ratio of branched alcohol:epichlorohydrin is at least about 3:1, preferably in the presence of a Group 1 A metal hydroxide and a phase transfer catalyst, followed by alkoxylation in the presence of an ionic catalyst. The branched alkyl chain may be saturated or unsaturated and may contain one or more heteroatoms. The repeating alkoxy units from the alkylene oxide are in the 2-position. The compositions are useful as surfactants, diluents, and the like, and may be less expensive than other branched surfactants.
