  • Low toxicity, low odor, low volatility solvent for agricultural chemical formulations
    Patent number: 10757940
    Abstract: An agricultural chemical composition comprises a solvent having the general formula CO(ORa)(Rb), wherein Ra is a linear or branched alkyl group of one to eight carbon atoms and Rb is an aromatic group. Active agricultural components are dissolved in the solvent to produce a solution usable for distributing the active components.
    Type: Grant

  • Using novel amines to stabilize quaternary trialkylalkanolamines
    Patent number: 10264785
    Abstract: New stabilizers for solutions of choline hydroxide and related quaternary trialkylalkanolamines are disclosed. The stabilizers are alkyl hydroxylamines, hydrazines, hydrazides, or derivates thereof, including compounds containing more than one such functionality. The new stabilizers are effective at concentrations less than about 1000 ppm, and choline hydroxide solutions stabilized with the compounds described herein typically have Gardner Color change less than about 2.0 after six months at reasonable temperatures.
    Type: Grant
