    摘要： A process for the production of 1,3-propanediol by hydrating acrolein in the presence of an ion exchanger to form 3-hydroxypropionaldehyde includes reacting acrolein and water in a ratio by weight of 1:2 to 1:20 at 30.degree. to 120.degree. C. and a pressure in the range from 1 to 20 bar, in the presence of an ion exchange hydration catalyst. The ion exchanger and any unreacted acrolein are separated from the reaction mixture. The 3-hydroxypropionaldehyde is then catalytically hydrogenated in a liquid or gas phase using hydrogenation catalysts. The ion exchanger hydration catalyst includes polyamine/polycarboxylic acid resins produced by reacting polyamine resins based on a crosslinked polyacrylamide matrix with acrylic acid, acrylic acid derivatives or a salt of an .omega.-haloalkanoic acid. An ion exchanger includes reaction product of reacting a polyamine resin based on a crosslinked polyacrylamide matrix with acrylic acid, acrylic acid derivatives or .omega.-haloalkanoic acid salts.

    摘要： THIS INVENTION RELATES TO OIL MODIFIED POLYURETHANE COATINGS AND THE PROCESS FOR MAKING SAID COATINGS, COMPRISING THE STEPS OF REACTING FROM ABOUT 0.95 TO 1.1 ISOCYANATE GROUPS ON AN ORGANIC POLYISOCYANATE WITH EACH HYDROXYL GROUPS ON A POLYOL, WHEREIN THE POLYOL IS FORMED BY REACTING FROM 1.1 TO 4 MOLES OF PHENOL WITH EACH MOLE OF AN ALDEHYDE SO AS TO FORM A NOVOLAK RESIN WHICH HAS FROM ABOUT 1.1/1 TO 2/1 PHENOLIC GROUPS PER ALDEHYDIC GROUP PER MOLECULE, ALKYLATING THE NOVOLAK RESIN WITH FROM ABOUT 0.1 TO 2 MOLES OF ALKYLATING AGENT PER MOLE OF PHENOLIC NUCLEUS ON THE NOVOLAK RESIN, HYDROXYALKYLATING THE NOVOLAK RESIN WITH FROM ABOUT 1 TO 6 MOLES OF HYDROXYALKYLATING AGENT PER MOLE OF PHENOLIC HYDROXYL ON THE NOVOLAK RESIN, AND ESTERIFYING OR TRANSESTERIFYING THE HYDROXYALKYLATED PRODUCT WITH FROM 0.33 TO 1 MOLE OF ESTERFYING OR TRANSESTERIFYING AGENT PER MOLE OF HYDROXYL ON THE HYDROXYALKYLATED PRODUCT. VARNISHES AND OTHER COATINGS CAN BE PREPARED FROM THE OIL MODIFIED POLYURETHANES OF THIS INVENTION AND EXHIBIT SUPERIOR RESISTANCE TO CAUSTIC.
