  • Publication number: 20120115730
    Abstract: Described are agrochemical compositions comprising alkoxylation products according to general formula (I) R1(CO)m—O—[R2O]nR3??(I) wherein R1 is a linear or branched, saturated or unsaturated, optionally hydroxy-functionalised hydrocarbyl radical containing 8 to 30 carbon atoms, R2 is an ethylene, propylene or butylene group or mixtures thereof, R3 is hydrogen or an acyl group containing 1 to 8 carbon atoms, m is 0 or 1, n is an integer between 3 and 100. When R3 is an acyl group, R2 is ethylene, propylene or mixtures thereof, and when R3 is hydrogen, R2 is ethylene, propylene, butylene or mixtures thereof provided that the terminal group represents a butylene oxide unit.

  • Patent number: 7825163
    Abstract: A process for making a biodegradable composition involving: (a) providing from about 20 to 80% by weight of C8-22 fatty alcohol; (b) providing from about 20 to 80% by weight of a ring opening product of a C8-18 1,2-epoxyalkane with ethylene glycol; (c) combining (a) and (b) to form a reaction mixture; and (d) reacting the reaction mixture with ethylene oxide, with the proviso that the ethylene oxide is used in an amount of from about 5 to 100 mol ethylene oxide per mol of free OH groups present in the reaction mixture.
