摘要:
THIS INVENTION IS CONCERNED WITH PHLOROGLUCINOL DERIVATIVES WHICH ARE REPRESENTED BY THE FORMULA:
(3,5-DI(R-O-)PHENYL)-O-CH2-(CH(-OH)N-CH2-OH
WHEREIN R IS LOWER ALKYL GROUP AND N IS 3 OR 1. THESE COMPOUNDS HAVING INTERESTING PHARMACOLOGICAL PROPERTIES ARE OBTAINED BY REACTING 3,5-DIALKOXY-PHENOL WITH EITHER GLYCOL CHLORHYDRIN OR GLYCEROL CHLORHYDRIN.
摘要:
THIS INVENTION IS CONCERNED WITH NEW PHLOROGLUCINOL DERIVATIVES OBTAINED BY CONDENSING A MOLECULE OF 1,3,5TRIHYDROXY-BENZENE WITH ONE OR TWO MOLECULES OR GLYCOL CHLORHYDRIN. (2-CHLORETHOXY) -3,5-DIHYDROXY-BENZENE HAS ANTISPASMODIC PROPERTIES AND 3,5-DI(2-CHLOROETHOXY)-PHENOL SHOWS TRANQUILISING ACTIVITIES.
摘要:
A PROCESS IS PROVIDED FOR THE PRODUCTION OF PHENYLHYDROXALKYL ETHERS SUCH AS PHENYLHYDROXYPROPYL ETHER, RESORCINO BIX(B-HYDROXYETHYL)ETHER, CATHERCOL BIX(B-HYDROXYETHYL)ETHER, HYDROQUINONE BIX(B - HYDROXYBUTYL)EHTER, PYROGALLO TRIS-(-HYDROXYETHYL)ETHER, AND PHLOROGLUCINOL TRIS(B-HYDROXYETHYL)ETHER BY REACTING AT ABIENT TO 110* C., A MONOHYDRIC, DIHYDRIC, OR POLYHYDRIC PHENOL SUCH AS PHENOL, RESORCINOL, CR PYROGALLOL AND AN EQUIVALENT OF ALKYLENE OXIDE, SUCH AS ETHYLENE OXIDE, PROPYLENE OXIDE, OR BUTYLENE OXIDE PER EQUIVALENT OF PHENOLIC HYDROXYL IN THE PRESENCE OF AN AQUEOUS MEDIUM HAVING A PH OF 8-13. THE PRODUCT IS RECOVERED IN HIGH YIELDS BY COOLING AND SEPARATING FROM THE MOTHER LIQUOR. THE MOTHER LIQUOR IS THEN RECYCLED TO SERVE AS THE AQUEOUS MEDOUM FOR A SUBSEQUENT REACTION. THE PREPARED COMPOUNDS HAVE AROMATICITY, AN ETHER LINKAGE, AND A REACTIVE HYDROXYL GROUP WHICH MAKE THEM USEFUL AS SPECIALIZED COMPONENTS IN POLYESTER AND POLYURETHANE RESIN FORMULATIONS.
摘要:
A diphenyl ether represented by the general formula (I), ##STR1## wherein R is a lower alkyl group having 1 to 4 carbon atoms, a lower alkoxyethyl group, the alkoxy substituent of which having 1 to 4 carbon atoms, or a lower alkoxyethoxyethyl group, the alkoxy substituent of which having 1 to 4 carbon atoms is capable of controlling annual and perennial weeds.
摘要:
Phenol ethers are prepared by reacting phenols with dialkyl carbonates in the presence of tertiary amines and/or phosphines. The aralkyl aryl ethers and alkyl aryl ethers obtained are starting materials for the manufacture of dyes, crop protection agents and scents.
