Catalytic synthesis of isoamyl butyrate with copper benzenesulfonate;

A series of 1,1-diacetic ester in yields of 59%～97% were synthesized from corresponding aldehydes and acetic anhydride using copper benzenesulfonate-acetic acid as synergistic catalyst at room temperature.

Two kinds of phenylsulfonylurea derivatives were designed and synthesized.

Fluoropyrimidinesulfuron is a phenylsulfonylurea herbicide, It has the profits of high efficacy, low residues, good selectivity.

By utilizing ethanoic acid and benzene sulfonic acid that are representative in organic acids as reagents to perform electrochemical enhancing pretreatment and floatation experiments on the coal of Zhenchengdi , find that both of their enhancing effects are striking.

One had an alkoxy benzene sulfonic acid group in the N-methylimidazolium cation,and the other possessed an alkyl benzene sulfonic acid group in the N-methylimidazolium cation.

Synthesis of p-nitro-ethylbenzoate with benzene sulfonic acid as catalyst is reported.

Study on the Methods of Tribenuron-methyl on Controlling Weeds in Yield of Summer Corns;

Influences of Isoproturon and Tribenuron-methyl on the Growth and MDA Content in the Leaves of Rice Seedlings;

Preliminary Study on the Resistance of Descurainia Sophia to Tribenuron-methyl in Hebei Province;

A RP-HPLC absolute calibration curve method for the determination of triasulfuron.

The metabolism of two sulfonylurea herbicides chlorsulfuron and triasulfuron was investigated by using wheat cytochrome P450 cDNA(CYP71C6v1) which expressed in yeast.

To evaluate the effect of triasulfuron and isoproturon residues to succeeding crops, including rice, corn, cotton and soybean, using the methods of field quantitative spraying, routine sampling and greenhouse potting.
