At first, 4-nitro-3-hexanol, 3-nitro-4-heptanol and 2-nitro -1-phenyl -1-propanol were synthesized with nitroalkane and aldehyde ; then they were reduced to 4- amino -3-hexanol, 3 amino -4-heptanol and 2- amino -1-phenyl -1-propanol with iron powder and concentrated HCl . The six title compounds as latent herbicide safener were prepared from amino alcohol, acetone and dichloroacetyl chloride with triethylamine as acid acceptor in the yield of 54.58%、74.39%、53%、79%、88.52% and 66.72%。 respectively. The structures of the compounds were confirmed by IR、 1H NMR、13C NMR and elemental analysis，and the compound of Ⅲc was further characterized by X-ray diffraction. The preliminary biological test show that the recovery rates of the plant height could attain 81.92% with 50μM of compound Ⅲc when the concentration of acetochlor in the soil was 10mg/kg.
