Basic information of MST® Reactive red 3BS Reactive red 3BS

Other names: Reactive red 3BS Reactive red 3BS, Reactive Red M-3BE, Reactive Red M-3BF, Reactive Red SP-3B, Reactive Brilliant Red ME-3BS

C.I.: Reactive Red 195

Molecular formula: C31H19ClN7Na5O19S6

Molecular weight: 1136.32

CAS: 93050-79-4

Molecular structural formula:


Reactive red 3BS Reactive red 3BS basic application performance

1. Solubility of Reactive red 3BS Reactive red 3BS:

There are 4 -SO3Na water-soluble groups on the Reactive red 3BS Reactive red 3BS dye matrix, so the solubility of Reactive red 3BS Reactive red 3BS is very good, the solubility is more than 100g/L at 50°C, and color spots rarely appear during application.

2. Reactive red 3BS Reactive red 3BS reactivity:

Reactive red 3BS Reactive red 3BS has two active groups: monochloros-triazine and vinylsulfone. Because the reactivity of vinylsulfone active groups is far greater than that of monochloros-triazine, under normal dyeing conditions, CI Reactive Red 195 and cellulose Among the reactive groups of fiber reaction, 80% is vinyl sulfone, and 20% is monochloro-s-triazine. The combination of dye and cotton fiber has stable acid resistance and relatively poor alkali resistance. But for C.I. Reactive Red 241, because vinyl sulfone is in the para-position, the reactivity is weak, the difference between vinyl sulfone and monochloro-s-triazine is small, and the combination of dye and cotton fiber has similar acid and alkali resistance. In general, the cost of dyes for para-esters is lower than that for meta-esters.

3. Reactive red 3BS Reactive red 3BS printing performance:

Reactive red 3BS Reactive red 3BS is used for printing. The best steaming time is 6 minutes. Because it is a double active base, the color is stable within 5-10 minutes and the change is not obvious. Because there are more water-soluble groups in the structure of Reactive red 3BS Reactive red 3BS, the floating color is easy to wash off, and the staining performance of the white background is also better.
