Preparation of 2, 5 - dichlorobenzonitrile method and special catalyst and its preparation method

The invention discloses a method for preparing 2, 5 - dichlorobenzonitrile method, the method comprises the following steps: 1) to dichlorobenzene with formaldehyde or/and paraformaldehyde as raw materials, in the chloromethylation and under the action of catalyst, through the chloromethylation reaction to obtain a chloromethylated product only 2, 5 - two chlorine animal pen chlorine; 2) the following steps 1) to obtain the product of 2, 5 - two chlorine animal pen chlorine as raw materials, with the ammonia gas, the oxygen in the catalyst under the action of the ammoxidation reaction 2, 5 - dichlorobenzonitrile. The invention also discloses a method for the preparation of 2, 5 - dichlorobenzonitrile method of special catalyst and its preparation method. The method of the invention compared with other methods, with the reaction raw materials are cheap and easy to obtain, by simple process, the reaction temperature is low, is friendly to the environment, a high degree of selectivity, higher advantage of the yield is high. Special catalyst with high selectivity and active; the preparation method is simple, low cost, has good thermal stability and mechanical strength, in the fixed bed and the fluidized bed reactor can be used on both.

METABOLISM OF CHLOROPHENYLALANINES IN CROP AND WEED PLANTS IN RELATION TO THE FORMATION OF POTENTIAL HERBICIDAL END PRODUCTS

Metabolism of 12 synthetic D,L-chlorophenylalanines has been examined in several crop and weed plants.Twenty-five gram samples of excised shoots or leaves of bushbean, soybean, corn, pigweed, lambsquarters, and giant foxtail were allowed to metabolize 10-4 M solutions of the D,L-chlorophenylalanines for 24 hr in continuous light.The plant samples were then extracted in 80percent methanol and the soluble acidic metabolites fractionated into ether.Each ether concentrate was partially purified by fractional elution from a PrepSep C18 coloumn and then analysed by HPLC.Collected fractions were esterified with pentafluorobenzylbromide and examined by GC-MS to demonstrate the presence of PFB-esters of chlorophenylacetic, chlorobenzoic and/or chlorocinnamic acids.Since certain of these metabolites are known to be potent plant growth-regulators and herbicides, the results are discussed in relation to the potantial herbicidal action of certain chlorophenylalanines by the mechanism of 'lethal synthesis'.Key Word Index - Phaseolus vulgaris; Glycine max.; Leguminosae; Zea mays; Amaranthus retroflexus; Chenopodium album; Setaria faberii; metabolism; D,L-chlorophenylalanines; chlorophenylacetic acids; chlorobenzoic acids; chlorocinnamic acids; growth regulators.
