Methods A serials of thiosemicarbazones were synthesized by utilizing aromatic aldehyde,aromatic ketone and thiosemicarbazide in aqueous solution under ultrasound irradiation.
The increase of concentration of inorganic electrolyte in aqueous phase can also markedly raise the solubilization capacity of sodium naphthenates for oil.
The authors discuss the applications of rosin and its derivant,including nonsulfide flotation and flotation separation of nonferrous metallic ions and organic compound from aqueous solution.
Aqueous titanium trichloride promoted intermolecular reductive cyclization of 1,2 -diketone and o-nitroaniline in basic media provides a convenient method for the synthesis of quinoxaline derivatives.
S-Methyl-isothiourea sulfate was oxidized by hydrogen peroxide to give methylsulfonyl chloride in 70% yield in aqueous hydrochloric acid solution.The product was characterized by 1HNNR and IR.
The perservative in liquid beverage was extrcated with n-hexane.The hexane layer was subjected to cyclodextrine polymer resin colume.The colume was eluted with aqueous solution of ethanol.
Methods The aqueous extract of all grass of Patrina villosa Juss was injected peritoneally to mice or that accompanied with suprathreshold or subthreshold dose of pentobarbital solution.
"In laboratory-scale studies, the data show that orange peel has a considerable potential for the removal of dyes from aqueous solutions over a wide range of concentrations," Bena?ssa says.
A divided flow cell is used for electrolysis of NaBr aqueous solution.The anolyte containing Br 2 and catholyte containing NaOH are produced simultaneously and in turn to epoxide HFP to HFPO.
