| abstract | (R1-M(-R2)(-R3)-R4)(+) Z(-) 1. A PROCESS FOR PREPARING ETHERS WHEREIN THE PROCESS CONSISTS ESSENTIALLY OF REACTING A CHLORINATED OR BROMINATED ALKANE CONTAINING FROM 1 TO 40 CARBON ATOMS WITH AN ALCOHOL AT A REACTION-PROMOTING TEMPERATURE, IN THE RANGE OF ABOUT 0 TO ABOUT 300* C., IN THE PRESENCE OF A CARALYST CONSISTING ESSENTIALLY OF A CATALYSTIC AMOUNT, IN THE RANGE OF FROM ABOUT 0.01 TO ABOUT 20 WEIGHT PERCENT BASED ON CHLORINATED OR BROMINATED ALKANE, OF AN ORGANIC QUATERNARY SALT, SAID PROCESS BEING CHARACTERIZED FURTHER IN THAT: (A) SAID ORGANIC QUATERNARY SALT IS REPRESENTED BY THE FORMULA: WHEREIN (1) M IS A PENTAVALENT ION OF AN ELEMENT SELECTED FROM THE GROUP CONSISTING OF NITROGEN AND PHOSPHOROUS, (2) R1, R2, R3, AND R4 ARE ALKYL GROUPS CONTAINING FROM 1 TO 40 CARBON ATOMS, (3) Z IS A CHLORIDE OR BROMIDE ANION, (B) SAID ALOCH9L IS SELECTED FROM THE GROUP CONSISTING OF: (1) ALKANOLS CONTAINING 1 TO 40 CARBON ATOMS, (2) ARYL-SUBSTITUTED MONOHYDROXY ALCOHOLS SELECTED FROM THE GROUP CONSISTING OF 3 -PHENYL BUTANOL, 4-PHENYL HEXANOL, 5-PHENYL OCTANOL, 3-PHENYL DECANOL, 6-PHENYL DODECANOL, 8-PHENYL HEXADECANOL, 10-PHENYL OCTADECANOL, 12-PHENYL EICOSANOL, 2-PHENYL - 2 - PROPANOL, 2-PHENYL-1 BUTANOL, 3-PHENYL-1-HEXANOL,, 6-PHENYL-1-HEXA NOL. 8-PHENYL-10-OCTANOL, 10-PHENYL-1-DECANOL, 6-PHENYL-DECANOL, 2-PHENYL-2-HEXANOL, 2-PHENLY-2-OCTANOL, AND 2-METHYL-2-PHENYL-1-BUTANOL, (3) POLYHYDRIXY ALCOHOLS SELECTED FROM THE GROUP CONSISTING OF ETHYLENE GLYCOL, PROPYLENE GLYCOL, GLYCEROL, 1,2-BUTANEDIOL, 1,3,5-HEXANEDIOL,1,3OCTANEDIOL, 1, 8-DECANEDIOL, 1, 3, 5,-HEPATANERTIOL, AND 1, 4,8-DECANETRIOL; AND (4) ALOXY-SUBSTITUTED ALCOHOLS REPRESENTED BY THE FORMULA ROCH2CH2OH WHEREIN R IS A C1 TO C6 ALKYL GROUP. |
