摘要:
NOVEL N,N''-BIS-TRIFLUOROMETHYLTETRAFLUOROETHYLENE DIAMINE AS PREPARED BY REACTING TETRACHLOROETHYLENE-1,2-BISISOCYANIDE DICHLORIDE WITH ANHYDROUS HYDROFLUORIC ACID UNTIL HYDROGEN CHLORIDE EVOLUTION CEASES. THIS NOVEL COMPOUND IS USEFUL IN ORANIC SYNTHESIS AND DIRECTLY AS AN INSECTICIDE.
摘要:
CHLOROTHIADIAZOLINES ARE PREPARED BY REACTING A MIXTURE OF AN ISOCYANATE AND AN ISOTHIOCYANATE WITH CHLORINE AT A TEMPERATURE OF FROM -20 TO +100* C. THE COMPOUNDS PRODUCED BY THE PROCESS ARE USEFUL AS HERICIDES AND FUNGICIDES.
WHERE X IS AS DEFINED ABOVE AND Y IS A NUMBER FROM 0 TO5 ARE PREPARED BY REACTING COMPOUNDS HAVING THE FORMULA:
R1-C(-Q)(-CL)-C(-Q)(-CL)-N=C(-R2)-CL
WHEREIN R1 AND R2 ARE AS DEFINED ABOVE AND Q IS CHLORINE OR TOGETHER REPRESENT A C-C- BOND; WITH SUBSTANTIALLY THE STOICHIOMETRICALLY NECESSARY QUANTITY OF SULPHUR AT A TEMPERATURE IN THE RANGE OF FROM 150 TO 350*C. SUCH CHLOROTHIAZOLES CAN BE USED FOR THE PRODUCTION OF PLANT PROTECTION AGENTS, ESPECIALLT AS INSECTICIDES.
摘要:
Dichloromethylenecarbonic acid esters and -thioesters are obtained by reacting dichloromethylenecarbamic acid chloride with alcohols, thioalcohols, phenols or thiophenols at a temperature range of from -50* to + 100* C. The compounds obtained by this process show pesticidal activity. They can, furthermore, be used for the preparation of the corresponding isocyanates.
摘要:
NON-IONIC FOAM STABILIZERS FOR POLYESTER POLYURETHANE FOAMS ARE OBTAINED BY LINKING HYDROPHOBIC AMINES OR AMIDES WITH POLYETHERS CONTAINING ETHYLENE OXIDE.
摘要:
ISOCYANATES CONTAINING AZIDE GROUPS WHERE THE AZIDE IS BONDED TO A HYDROCARBON ORGANIC RADICAL OR HYDROCARBON ORGANIC RADICAL INTERRUPTED BY ACYL, ETHER OR THIOETHER GROUPS AND THE ISOCYANATE GROUP IS BONDED DIRECTLY TO A CARBON ATOM. A PROCESS FOR THE PREPARATION OF THESE ISOCYANNATES WHICH INVOLVES THE PHOSGENATION OF THE CORRESPONDING AMINES IS ALSO DISCLOSED. THE ISOCYANATE-CONTAINING AZIDE GROUPS ARE INTENDED TO BE USED IN PREPARATION OF LIGHT SENSITIVE POLYMERS AND AS INTERMEDIATE PRODUCTS FOR THE PREPARATION OF PESTICIDES AND PHARMACEUTICALS.
摘要:
COMPOSITIONS USEFUL AS ADHESIVES HAVING IMPROVED BONDING CHARACTERISTICS ARE PREPARED FROM NATURAL OR SYNTHETIC RUBBER BINDERS AND A DIPHENYLMETHANE TETRAISOCYANATE DERIVATIVE.
