The crystal is transformed into anhydrous sodium sulfite after separating,cleaning and drying.

A new class of inionic surfactants—fluorocarbon alkyl sulfosuccinate monoester were prepared on the basis of maleic anhydride,fluoro-alcohol and anhydrous sodium sulfite as starting materials by means of esterification and sulphonation.

OBJECTIVE To establish the quality standard for the bacterial endotoxins test of four antioxidants(anhydrous sodium sulfite,sodium bisulfite,sodium pyrosulfite and sodium thiosulfate).

Desizing process of cotton fabric by ammonium persulfate-sodium bisulfite system;

Effects of foliage spraying sodium bisulfite on photosynthetic physiological characteristics of Citrus sinensis with sulphur deficiency;

In the synthesis of menadione sodium bisulfite(MSB),the traditional raw material 2-meth- yl-1,4-naphthoquinone(2-MNQ) contains 6-methyl-1,4-naphthoquinone(6-MNQ),resulting in lower content of the product.

Determination of Sodium Hydrogen Sulfite in Compound Amino Acid Injection by Colorimetry;

To study the specification of sulfite involved with prawn preservation in the processing,the residues of SO2 content in prawn(Litopenaeus vannamei) which treated with variable concentrations and soak time of sulfite(sodium sulfite and sodium hydrogen sulfite) were studied during storage.

The introduction of this text is as the taw materials with monglphenol polyoxyethylene ether、cis-butenediois anhyclride、sodium hydrogen sulfite,formate the sodium POE nonylphenol ether sodiosulfosuccinate method under catalyst function,and the range of application of the products,and has discussed about relevand question.

The current status of flue gas desulfurization in our country was analyzed,and the significance of using SO2 in flue gas to prepare NaHSO3 was discussed.

In order to establish chemical regulating cultivation technology for high yield of peanut,the leaves of potted peanut was sprayed with different concentrations of NaHSO3 at early flowering stage.

Effects of NaHSO3, CO2, potassium on photosynthesis of crops were discussed, and transformation of C3 crops\' hereditary features was also discussed according to C4 pathway mechanism.
