Abstract:
2-HALOETHYLPHOSPHONATE DIESTERS ARE PREPARED FROM 1-CHLORO-2-BROMO-ETHANE AND AN ALKALI METAL SALT OF A SECONDARY PHOSPHITE WHEREIN THE REACTION IS CARRIED OUT IN THE PRESENCE OF AN APROTIC, DIPOLAR SOLVENT SUCH AS N-METHYL-2-PYRROLIDONE. SAID DIESTERS ARE READILY HYDROLYZED TO -2-CHLOROETHYLPHOSPHONIC ACID USEFUL AS A PLANT GROWTH STIMULANT.
Abstract:
Plant growth regulating compounds are N-substituted-P-(2chloroethyl)-phosphonamidic esters of the formula: WHEREIN R1 is halophenyl and R2 is alkyl or haloalkyl. They are prepared by the reaction of 2-chloroethylphosphonohalidic esters with the appropriate haloaniline.
Abstract:
A WATER SOLUBLE DYESTUFF CONTAINING AT LEAST ONE QUATERNIZED FIBER-REACTIVE A,B-DICHLORACRYLAMIDE GROUP OF THE FORMULA
NH-CO-CCI=CH-NR1R2R3CL
WHEREIN R1, R2 AND R3 REPRESENT MONOVALENT ALIPHATIC RADICALS OF NO MORE THAN ABOUT 8 CARBON ATOMS OR AT LEAST TWO OF R1, R2 AND R3 TAKEN TOGETHER, REPRESENT THE ATOMS NECESSARY TO FORM WITH THE DEPICTED ADJACENT N ATOM A HETEROCYCLIC RING, AND A METHOD OF DYEING THEREWITH.
Abstract:
Process for the production of diesters of 2hydroxyethylphosphonic acid by reaction of alkali metal salts of secondary phosphites and ethylene oxide wherein the reaction is conducted in the presence of an aprotic, dipolar solvent in which the dipole moment of the solvent is 3.5 Debye units or greater. Such diesters are useful as intermediates for the production of the plant stimulant 2-chloroethylphosphonic acid.
Abstract:
A hardened gelatin composition and a method of hardening said gelatin composition wherein the gelatin is hardened by the addition of a pyrrolidonyl polyacrolein-bisulfite addition compound.
