  • Trialkyldithiocarbamates and method of making same
    Patent number: 4269785
    Abstract: Disclosed herein are improved, water-soluble compounds of the formula: ##STR1## wherein R and R' are each alkyl groups containing from 1 to 6 carbon atoms and R" is hydrogen or an alkyl group of 1 to 6 carbon atoms, said compounds forming clear solutions with no side reaction products present. A process for the preparation of the above compounds comprises reacting 2 moles of at least a mono- or dialkylamine with one mole CS.sub.2, in water, and within a reaction chamber which is preferably closed, for a period of time sufficient to cause the pressure therein to fall below normal atmospheric pressure.
    Type: Grant
    Filed: July 18, 1979
    Date of Patent: May 26, 1981
    Inventor: Lawrence H. Nash
  • Piperidinyldithiocarbonic acid derivatives
    Patent number: 4175194
    Abstract: Compounds of the formula: ##STR1## wherein R is selected from the group consisting of S.sub.x, (wherein x is a whole number from 1 to 3), SO, SO.sub.2, S.sub.2 O.sub.3, S.sub.2 O.sub.4, S.sub.2 O.sub.5.
    Type: Grant
    Filed: June 2, 1978
    Date of Patent: November 20, 1979
    Inventor: Lawrence H. Nash
  • Bis halogenated phenoxyalkanoates and the method of making same
    Patent number: 4093664
    Abstract: Compounds useful as plant growth regulators having the formula: ##STR1## WHEREIN X and X' are each halogens, R and R' are each alkyl groups containing from 1 to 4 carbon atoms and n and n' each have a value from 1 to 5. Method of preparing said compounds is also disclosed.
    Type: Grant
    Filed: October 18, 1976

  • Dialkylammonium-2,4-dichlorophenoxyacetates as plant growth regulators and the method of making same
    Patent number: 4001006
    Abstract: Various dialkylammonium-2,4-dichlorophenoxyacetates having the formula ##STR1## wherein R.sub.1 and R.sub. 2 are radicals each selected from the group consisting of methyl and ethyl, are useful as plant growth regulators. Mono-substituted alkylamines are not suitable for processing into compounds of this invention. The compounds of the invention exhibit excellent water solubility characteristics and possess an exceptionally high and unexpected degree of effectiveness as a general weed killer on lawns, pasture lands, ponds, lakes, canals, ditches, etc. Methods of using and preparing these compounds are disclosed.
