    摘要: A selective process for the preparation of diphenylmethane bis(dialkylureas) is disclosed. An alkyl phenylcarbamate or an N,N-dialkyl-N'-phenylurea is reacted with a methylene bis(alkyl carbamate) in the presence of an acid catalyst. The use of a staged addition of phenylcarbamate or phenylurea to the methylene bis(carbamate) and the use of a ramped temperature program are the keys to good selectivity to MDI dimer products.

    摘要: Expandable styrene polymer particles which have anti-static and anti-lumping properties during expansion and after molding into an article are produced by adding 0.1 to 0.4 parts of trialkyl alkylalkoxylated quaternary ammonium salts, per 100 parts of polymer particles by coating of the expandable polymer particles with the salts. The salts may be added as sole antistatic agent or in addition to the known internal additives which impart fast-cool and anti-lump properties.

    摘要: Alkoxylated ether sulfate anionic surfactants of this invention are prepared by conventional procedures, e.g., oxyalkylation with propylene oxide or 1,2-butylene oxide of a straight chain plasticizer range alcohol; optionally followed by oxyalkylation with ethylene oxide or with a mixture of ethylene oxide and higher alkylene oxide; sulfation of the alkoxylated product; and neutralization of the sulfated derivative. The alkoxylated ether sulfate anionic surfactants of the present invention are liquids which exhibit superior detergency to polyester fabrics, excellent hard water stability, organic solubility, low foaming, low odor, and exhibit excellent compatibility with non-ionic and other surfactants in detergent formulations.
