Abstract:
A single-stage process for the production of &agr;-hydroxy ethers according to formulae (I) and (II) by oxidation of olefinic substrates with organic hydroperoxides and opening of the resultant oxirane ring by mono- or polyhydric alcohols, wherein molybdenum compounds in combination with a compound selected from the group consisting of boron trifluoride, alumina, 1,8-diazabicyclo-[5.4.0]-undec-7-ene, 1,4-diazabicyclo-[2.2.2]-octane and mixtures thereof are used as a catalyst system and a catalyst support selected from the group consisting of amorphous alumino-silicates and zeolites is used, and whereinR1, R2, R4, and R6, independently of one another, are saturated, unbranched or branched hydrocarbon radicals having 1 to 22 carbon atoms, or are completely or partially fluorinated hydrocarbon radicals having 1 to 22 carbon atoms, R3 represents a mono- or polyhydric, linear or branched radical of an alcohol having 1 to 22 carbon atoms which may be fluorinated wholly or in part, R5 is spacer consisting of an unbranched or branched chain with 2 to 100 carbon atoms which contains 0 to 20 oxygen atoms, 0 to 20 nitrogen atoms, 0 to 4 sulfur atoms, and 0 and 3 phosphorus atoms and which has 0 to 20 hydroxyl, carbonyl, carboxyl, amino and/or acylamino groups, and X and Y, independently of one another, are substituents according to formula XVIâ€”(C2H4O)&agr;(C3H6O)&bgr;Hâ€ƒâ€ƒ(XVI) where &agr;=0 to 50 &bgr;=0 to 60 and &agr;+&bgr;=1 to 100 and wherein the alkoxide are incorporated randomly or blockwise and the sequence is optional, or are substituents according to formula XVIIâ€”(C2H4O)&ggr;(C3H6O)&dgr;-FRâ€ƒâ€ƒ(XVII) where each &ggr;=0 to 20 &dgr;=0 to 20 and &ggr;+&dgr;=0 to 40 and FR represents a functional radical â€”CH2â€”COOM, â€”SO3M, â€”P(O)(OM)2, â€”C3H6â€”SO3M, or â€”Oâ€”C(O)â€”C2H3(SO3M)â€”CO2Mâ€², wherein M, Mâ€² are equal to alkali, ammonium, alkanol ammonium or Â½ alkaline earth metal, and the alkoxide units, too, are incorporated randomly or blockwise and the sequence is optional.
