  • Patent number: 4217296
    Abstract: Novel sulfate salts of C.sub.10 -C.sub.20 linear alkyl glyceryl ether alcohols, useful as biodegradable surfactants in detergent compositions, are prepared by reacting a stoichiometric excess of C.sub.10 -C.sub.20 linear alkyl alcohol with glycidol predissolved in hexyl acetate, to selectively produce C.sub.10 -C.sub.20 linear alkyl glyceryl ether alcohols containing 1-3 glyceryl units, sulfating said ether alcohols, and neutralizing the sulfates with base.

  • Patent number: 4210764
    Abstract: Cresylic acid (phenol or alkylated phenols) is used to promote barium oxide or hydroxide which is used as an ethoxylation catalyst for the reaction of ethylene oxide and alkanols of all classes. The reaction is carried out at temperatures of from about 150.degree. to about 200.degree. C. to yield the ethoxylated product. The product obtained has a very narrow high adduct distribution with low levels of by-products and unreacted free alcohols. Calcium and magnesium oxides show negligible catalytic effect.

  • Patent number: 4188305
    Abstract: A surfactant which is the condensation product of a fatty alcohol containing from 17 to 19 carbon atoms with from about 6 to about 15 moles of ethylene oxide, the distribution of the ethylene oxide condensation products being such as to give more than about 50% by weight within .+-.2 ethylene oxide moieties of the average, preferably, no single condensation product (a single specific number of ethylene oxide moieties) constituting more than 50% by weight of the product; automatic dishwasher compositions containing said surfactant.

  • Patent number: 4187384
    Abstract: Mono- and poly-ethylene glycol dialkyl ethers IR.sup.1 --O--(--CH.sub.2 --CH.sub.2 --O--).sub.n --R.sup.2where R.sup.1 is C.sub.1 -C.sub.4 -alkyl, R.sup.2 is C.sub.3 -C.sub.5 -alkyl and n is from 1 to 100, are prepared by reacting monoalkyl ethers IIR.sup.1 --O--(--CH.sub.2 --CH.sub.2 --O--).sub.n --Hwith a C.sub.3 -C.sub.5 -olefin III in the presence of an acid ion exchanger at from 1 to 200 bar and from 40.degree. to 150.degree. C., the reaction being started at from 100.degree. to 150.degree. C. and the temperature then being lowered, in at least two approximately equal steps, to from 40.degree. to 80.degree. C., the temperature being dropped in each case to the next-lower level when the conversion per unit time no longer changes significantly.
