摘要:
Processes for preparing alkoxylated nonionic surfactants are disclosed, wherein a compound having at least one active hydrogen atom, a carboxylic acid ester or mixtures thereof are reacted with an alkylene oxide in the presence of a hydrotalcite catalyst to form a reaction product mixture; and the reaction product mixture is combined with an acid in at least an equimolar amount based on the amount of the catalyst present.
摘要:
Random fatty alcohol alkoxylates with low temperature stability which are polymerization products of fatty alcohols, ethylene oxide and propylene oxide, according to the general formula (I): R1O[(EO)n(PO)m]—H (I) wherein R1 represents an alkyl group having from about 6 to about 22 carbon atoms, each EO represents —CH2CH2O—, each PO independently represents —C(CH3)HCH2O— or —CH2C(CH3)HO—, wherein n represents the average number of EO units present in each random fatty alcohol alkoxylate and has a value of from about 2 to about 7, and wherein m represents the average number of PO units present in each random fatty alcohol alkoxylate and has a value of from about 1.5 to about 3; are disclosed. A process for the production of such random fatty alcohol alkoxylates and methods of their use in water-dilutable concentrates are also disclosed.
摘要:
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.
