How to Increase solubility for Solvent Dyes.

[shreenathci]

Dear friends,

 

please help me to increase solubility of Solvent dyes especially Solvent Blue-48. What process should I take care of during manufacturing and reaction and how to change the tone of the dye from redder to greener?

Can Any one help me.

For those who also wonder what we're talking about: I did a little Google search...

 

Solvent Blue 48 is an "Amine salt of Sulfonated Copper Phthalocyanine with clean deep blue shade."

 

From the same website:

 

Solubility:

-Acetone : 9%

-Cellosolve : 9% (Cellosolve = ethylene glycol monoethyl ether)

-Ethanol : 8%

 

Applications :

-Alcoholic Solvents

-Spirit Lacquers

-Flexographic Inks

 

The next thing I want to know: you want to increase the solubility of this "Solvent Blue 48", in what? Ethanol? Water? Another solvent?

Dear friend

I want to know how to increase solubility of Solvent Blue 48 in ethanol and cellosolve. Also if you know tell what steps should I keep in mind while manufactring Solvent Ble 48.

 

Plz help me.

It will dissolve better in hot solvent (but be aware of the fire risk).

It may be possible to change the base and thereby produce a more soluble derivative but that would need to be sorted out experimentally.

I seem to remember that chlorinated phthalocyanines are greener than unsubstituted ones. However producing these isn't going to be trivial.

Might it not be easier to find a different dye/pigment?
