JF Dispersant MF POWDER Product Introduce:

Synonyms: CAS No.:9084-06-4

Dispersant MF is an anionic surfactant, dark brown powder, soluble in water, soluble in water, acid, alkali and hard water, it mainly works as dispersant and additive in disperse dyestuff, vat dyestuff and reactive dyestuf,easy to absorb moisture, nonflammable, with excellent dispersant and thermal stability, no permeability and foaming, resisting acid and alkali, hard water and inorganic salts, no affinity for fibers such as cotton and linen; have affinity for proteins and polyamide fibers; can be used in conjunction with anionic and nonionic surfactants, but not in combination with cationic dyes or surfactants.

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.

Application:

1. Mainly used for vat dyes, disperse dyes, reactive dyes as dispersing agent.
2. It can also be used in wettable pesticide.
have a good grinding effect, high pigmentation power, high dispersion force and excellent thermal stability and so on.
3. It can also be used for textile printing and dyeing, pesticides, architecture, ceramics, rubber, paper, oil drilling, carbon black, water treatment and other industries as dispersing agent.
4. It can also be used as a stabilizer for rubber industrial latex, and as an auxiliary for the leather industry.
5. Dispersing agent MF is soluble in concrete as a high range water reducing agent, which can shorten the construction period, save cement, save water and increase cement strength.
