DIHYDROCHLORIDES OF DERIVATIVES OF 2-OXYETHYLAMINES HAVING ACTIVITY AS GROWTH STIMULATOR FOR POTATOES Russian patent published in 1995 - IPC

FIELD: agriculture. SUBSTANCE: dihydrochloride of 1,4-di{1-[N-(2-oxyethyl) amino] cyclohexyl-1} butadiene has essential formula C₂₀H₃₄C₁₂N₂O₂, its melting point is 264-266 C. Yield is 74.2%. Dihydrochloride of 2,7-dimethyl-2,7-di [N-2- (oxyethyl)amino]-3,5-octadiene has essential formula C₁₄H₂₆C₁₂N₂O₂, its melting point is 218-220 C. Yield is 87.2%. RR₁C(NHCH₂CH₂OH) ≡ CH where RR₁C-cyclohexyl, R=R₁=CH₃ is used as reagent 1. Oxygen is used as reagent 2. Reaction is carried out in the presence of CuCl and NH₄Cl within 13-16 h in the medium of H₂O - C₂H₅OH. The process is followed by cooling to 0 - (-5) C and by treatment with 25% NH₄OH within 1 h. After recrystallization thus prepared base is dissolved in ethanol and is treated by HCl to acid reaction. EFFECT: improves quality of desired product. 2 dwg, 8 tbl
