Abstract:
IN THE PRODUCTION OF HAOGEN-CONTAINING POLYARYL ESTERS BY THE POLYCONDENSATION OF HALOGEN-CONTAINING DISPHENOLS AND AROMATIC ACID DICHLORIDES IN THE PRESENCE OF A CATALYST COMPRISING A TETIARY AMINE, AN AID AMIDE OR MIXTURES THEREOF, THE IMPROVEMENT WHICH COMPRISES EFFECTING THE CONDESATION IN THE PRESENCE OF ABOUT 0.001 TO 50 MOLEPERCENT BASED ON THE ACID DICHLORIDE, OF AT LEAST ONE ACTIVATOR SELECTED FROM THE GROUP CONSISTING OF MAGNESIUM COMPOUNDS, AND OXIDES, CHLORIDES OR HYDROCHLORIDES OF CU, ZR, SN, TN, V, PB AND FE. THE CONDENSATION IS PREFERABLY EFFECTED IN SOLUTION USING AS ACTIVATED CUO, CUCI, ZRCI4, SNCL2, TICL4, COCI3, PBO, FE2O3 OR AN ALLOY OF MG, CU, ZR, SN, TI, V, PB OR FE. IN THIS MANNER HIGH MOLECULAR WEIGHT CAN BE ATTAINED IN SHORT REACTION TIMES.

Abstract:
Phosphorus-containing compounds, especially alkyl phosphates, of the formula wherein A is oxygen or sulfur, g and n are 0 or 1, and R1, R2 and R3, which may be the same or different, are alkyl, cycloalkyl or aryl wherein R1 may be substituted with one or more halogen atoms; are formed from the corresponding halo- or halo-alkoxyphosphorus compounds and a hydroxy-containing organic compound by reaction therebetween under gradual increase of temperature and simultaneous decrease in pressure, over an organo oxy compound catalyst comprising an element of Group II, IV or V of the Periodic System having an atomic number of between 12 and 83, in amounts of from 0.001 to 2 per cent by weight, based on the amount of starting phosphorus compound reactant.
Abstract:
Novel halophenoxy-s-triazine derivatives and salts thereof characterized by improved solubilities having the formula:-
WHEREIN X represents from one to five halogen atoms and R1 is either of
WHEREIN R2 is alkyl having one to five carbon atoms, halogenated alkyl having one to five carbon atoms, alkali metal or ammonium, R3 is hydrogen, alkyl having two to 18 carbon atoms, halogenated alkyl having two to 18 carbon atoms or cycloalkyl, and R4 is alkyl, cycloalkyl, aryl, halogenated alkyl, halogenated cycloalkyl or halogenated aryl, and wherein R3 and R4 taken together with the nitrogen atom to which they are attached form a heterocyclic ring. The novel triazine derivatives and their salts are suitable for use as water repellants, parting agents, textile adjuvants, as fire retardants, fungicidal, phytotoxic, bactericidal and insecticidal agents.
