DERIVATIVES OF MEPIQUATE BORATE, METHODS FOR THEIR PREPARING, ELECTROCHEMICAL METHOD FOR PREPARING N,N-DIMETHYLPIPERIDINIUM, SUSPENSION CONCENTRATE POSSESSING PLANT GROWTH-REGULATING EFFECT Russian patent published in 2006 - IPC C07D295/37 C01B35/12 A01N59/14 A01N33/12 A01P21/00 

FIELD: chemistry of metalloorganic compounds, agriculture.

SUBSTANCE: invention describes derivatives of mepiquate borate of the general formula (I): wherein DMP means N,N-dimethylpiperidinium (mepiquate); M means metal cation acceptable for agriculture and chosen from a series comprising sodium, potassium, magnesium, calcium, zinc, manganese or copper, hydrogen atom or NH₄ ⁺; O means oxygen atom; A means chelate of complex-forming fragment bound with one boron atom and representing (lower)-alkylglycols or sugars; n and m mean similar whole numbers in the range from 1 to 6; x means a whole or fraction number in the range from 0 to 10; y means a whole or fraction number in the range from 1 to 48; z means a whole or fraction number in the range from 0 to 48; v means a whole or fraction number in the range from 0 to 24, and w means a whole or fraction number in the range from 0 to 24. Also, invention describes methods for preparing compound of the formula (I) by interaction of N,N-dimethylpiperidinium hydroxide with boric acid and/or boron-containing oxides and optionally with metal hydroxides acceptable for agriculture indicated above or electrochemical method involving interaction of N,N-dimethylpiperidinium halide in the presence of water and boric acid and in the presence metal hydroxides acceptable for agriculture by bipolar electrodialysis. Invention describes electrochemical method for preparing N,N-dimethylpiperidinium hydroxide and a suspension concentrate possessing the plant growth-regulating effect prepared by mixing N,N-dimethylpiperidinium hydroxide, boron-containing compound chosen from boric acid and borate salt with a thickening agent and water, or by mixing compound of the formula (I) with Na₂B₈O₁₃ x 4 H₂O, a thickening agent and water. Prepared derivatives of mepiquate borate possess the improved indices of hygroscopicity and corrosion activity.

EFFECT: improved preparing methods, valuable properties of derivatives.
