Abstract: The present invention relates to an herbicide composition, which adds bismuth gelatinzer to a bipyridylium diquaternary salt. Bismuth gelatinzer will form a protecting membrane of a colloidal or dispersed object on the surface of stomach tissue; it is capable of lowering the absorption of bipyridylium diquaternary compound to gastrointestinal tracks then reducing the oral toxicity of bipyridylium diquaternary herbicide.

Abstract: The invention discloses a dried glyphosate granule herbicide composition, comprising 50˜950 g/kg glyphosate, 5˜950 g/kg non-inorganic salt extender, and 0.5˜150 g/kg organo-silicon surfactant. The herbicide according to the present invention uses glyphosate as the active ingredient without turning it into salt derivatives, hence reducing the cost of preparation. The present invention also provides a method for preparing the glyphosate herbicide disclosed.

Abstract: The invention features sporamin promoters, including the promoter of the Ipomoea batatas sporamin A gene. The promoter directs gene expression in tubers and responds in aerial structures to wounding, pathogens, and other environmental insults.

Abstract: A process for preparing 3,4-dihydroxybenzonitrile includes the steps of reacting a nitrile compound with an alkali metal halide, followed by treating with an acid.

Abstract: A process for preparing triazolopyrimidine derivatives of the formula (I): wherein R1 represents a hydrogen or an alkyl radical of one to ten carbon atoms, or a cycloalkyl radical of three to six carbon atoms, or an alkenyl radical of up to four carbon atoms; R2 represents a hydrogen, a halogen atom, a hydroxyalkyl or alkyl radical of one to ten carbon atoms; R3 represents a hydrogen, a hydroxyalkyl or alkyl radical of one to four carbon atoms; by rapidly preparing diamino-1,2,4-triazole which is reacted with an aldehyde to form an imide which is reacted with an &agr;,&bgr;-unsaturated acid derivative, the reaction product of which is hydrolyzed in the presence of an acid to produce the triazolopyrimidine derivatives of formula (I). The compounds of the formula (I) are capable of preventing bronchospasm.

Abstract: A heterocyclic compound has the following formula (I) wherein Y represents a substituted or unsubstituted ethylene group or a trimethylene group, W represents the group —SO2R1, X represents an oxygen atom or sulfur atom or the group —NR2 or —CHR3, R represents a hydrogen atom or a methyl group and Z represents a pyridyl group.

Abstract: A process for preparing alkoxy- and aryloxy-phenols involves the steps of reacting a benzaldehyde derivative with a peracid to form a benzodioxole derivative, removing non-reacted peracid from the reaction mixture, and reacting the benzodioxole derivative in the reaction mixture with a hydrolyzing agent.

Abstract: A process for preparing imidacloprid involves reacting 2-nitroiminoimidazolidine with 2-chloro-5-chloromethyl pyridine in the presence of an alkali carbonate in an organic solvent. A stoichiometric amount of the 2-chloro-5-chloromethyl pyridine is gradually added into mixture of a corresponding stoichiometric amount of the 2-nitroiminoimidazolidine and the organic solvent under reflux condition.

Abstract: A liquid detergent composition contains (1) 0.5 to 5% by weight of citrate, (2) 0.5 to 10% by weight of alcohol, (3) 5 to 15% by weight of cocinin, and (4) 70 to 94% by weight of water.

Abstract: A process for preparing 2-oxindole includes catalytically reacting isatin with hydrazine hydrate in a polar solvent containing a dissolved weak base at an elevated temperature to form the 2-oxindole product.
