摘要:
AN IMPROVED STABILIZED COMPOSITION COMPRISES A SYNERGISTIC COMBINATION OF AN ORGANIC THIOANHYDRIDE AND A MONOHYDROCARBYL TIN COMPOUND OF THE FORMULA
R3SN(Z)N(Z1R4)3-2N
WHEREIN R3 IS A HYDROCARBYL RADICAL HAVING 1 TO 12 CARBON ATOMS, Z AND Z1 ARE EITHER OXYGEN OR SULFUR, R4 IS HYDROGEN OR AN ORGANIC RADICAL BONDED TO Z1 BY A CARBON ATOM AND N IS A NUMBER FROM 0 TO 1.5 VARYING IN INCREMENTS OF 1/2. HALIDE CONTAINING RESINS STABILIZED WITH THESE COMPOSITIONS EXHIBIT IMPROVED RESISTANCE TO THE DEVELOPMENT OF EARLY COLOR DURING PROCESSING.
ARE PREPARED WHERE R1 AND R4 ARE HYDROGEN, ALKYL, ARYL HALOARYL, HALOALKYL, ARALKYL, FURYL, TETRAAHYDROFURYL AND R2 AND R5 ARE ALKYL, ARYL, HALOARYL, HALOALKYL, ARALKYL, FURYL, TETRAHYDROFURYL OR
R1-C-R2
TOGETHER IS CYCLOALKYL OF AT LEAST 3 CABON ATOMS AND
R4-C-R5
TOGETHER IS CYCLOALKYL OF AT LEAST 3 CARBON ATOMS, R3 IS ALKYLENE OR ARYLENE, N IS 0 OR 1 AND X IS HALOGEN. THE COMPOUNDS ARE USEFUL AS DRIERS FOR ALKYD RESINS AND TO ACCELERATE THE OXIDATIVE POLYMERIZATION OF OLEFINIC POLYMER SYSTEM, PARTICULARLY UNSATURATED POLYESTERS, IN CONJUNCTION WITH ORGANIC PEROXIDES. THE COMPOUNDS CAN ALSO BE USED TO FORM MIXED BIDENTATE LIGAND CHELATES AS WELL AS MIXED BIDENTATE UNIDENTATE LIGAND CHELATES OF THE FORMULA
(CO(II)(AZ)8Y)M(Z)4-2M)X2
WHERE AX IS R1-C(-R2)=N-N=(R3=N-N=)N-C(-R4)-R5 WHICH HAVE THE SAME USE.

ALKYL SUBSTITUTED PYRROLES AND PYRAZOLINES ARE PREPARED BY TREATING A KETAZINE OR ALDAZINE WITH A METAL HALIDE OF THE FORMULA MX2 WHERE M IS COBALT OR NICKEL AND X IS A HALOGEN A TEMPERATURE OF 10 TO 300*C.
摘要:
Bis (monoalkyltin) orthosulfites, of the formula WHEREIN R is an alkyl preferably having one to 12 carbon atoms and Z is hydroxy or a monovalent or divalent organic radical bonded to the tin through an oxygen or sulfur atom and can be prepared by oxidation of monoalkylthiostannoic acids with organic hydroperoxides, optionally followed by condensation with various functional groups. These novel orthosulfites are useful as condensation, polycondensation and polymerization catalysts; as fungicides, bactericides and stabilizers for synthetic polymers.
摘要:
There are prepared monohydrocarbyltin mercaptocarboxylates of the formula
AND TRIHYDROCARBYLTIN MERCAPTOCARBOXYLATES OF THE FORMULA
WHERE R, R1, R2 and R3 are alkyl, aralkyl or aryl, R'' is H, Na, K or
N IS 1 TO infinity AND M IS 1 TO 3. The compounds are useful as catalysts in polymerization, e.g. in forming polyesters, and as biocides, e.g. as fungicides and bactericides.
