Dispersant MF(formaldehyde condensation) is brown to dark brown powder, belonging to anionic surfactant. Soluble in water, resistant to acid, alkali and hard water, with good grinding effect, high coloring power, strong dispersion, excellent heat stability and other characteristics. It is mainly used as dispersant in disperse dyes, VAT dyes and reactive dyes, and can also be mixed with various anionic surfactants, which is suitable for the commercial requirements of various disperse dyes.

Dispersant MF Production Method:

The preparation process of dispersant MF includes three steps: sulfonation of methyl naphthalene, condensation of sulfonated product with formaldehyde, and neutralization. 500kg methylnaphthalene was put into the sulfonation kettle, heated and melted, then stirred, heating to 130~140℃, and then 210L water was added under rapid agitation, and then stirred for half an hour to sample the acidity. If the total acidity was 25%~27%, it was qualified. ; Cool to 90~100℃. Add 37% formaldehyde solution 300kg at a time. The reaction temperature is 130~140℃ and the pressure is 0.15~0.20mpa. React 2h to allow it to fully condense. After condensation, add 30% lye for neutralization until PH value is about 7, cool crystallization filtration, dry crystallization is the finished product.

Dispersant MF Quinoline determination method:

Determination of quinoline in dispersant MF by gas chromatography-mass spectrometry. Xylene was used as extraction solvent, solid phase extraction was used for pre-treatment, and internal standard method was used for quantification. This method has good linearity, low detection limit, high recovery rate, good precision and accurate qualitative and quantitative analysis.
