How do you dissolve phthalocyanine?
You can try THF, chloroform or dichloromethane etc. Beside it is very interesting that your phthalocyanine is water soluble, you can use Dimethylsulfoxide (DMSO) or Dimethylformamide (DMF) to solve. DMF is quite good solvent you may use it to dissolve your phthalocyanine.
Is Phthalo blue the same as phthalocyanine blue?
Phthalo blue (or Phthalocyanine Blue BN) is an organic blue developed by chemists under the trade name “monastral blue”. They’re lightfast, and an ideal pure blue for it absorbs light almost completely except for the green and blue bands. There are other phthalocyanine colors as well, which are equally lightfast.
Why is a solution of metal free phthalocyanine dye blue?
Substituted phthalocyanine complexes often have much higher solubility. They are less thermally stable and often can not be sublimed. Unsubstituted phthalocyanines strongly absorb light between 600 and 700 nm, thus these materials are blue or green.
Is phthalocyanine blue toxic?
Copper: Phthalo Blue & Green. Harmful if inhaled or swallowed. Nickel. Cumulative exposure leads to poisoning and nerve damage.
How do pigments dissolve?
Pigments are generally not soluble in water, oil, or other common solvents. To be applied to a material, they are first ground into a fine powder and thoroughly mixed with some liquid, called the dispersing agent or vehicle.
What is phthalocyanine used for?
Phthalocyanines are the second most important class of colorant, and copper phthalocyanine is the single largest-volume colorant sold. Traditional uses of phthalocyanine colorants are as blue and green pigments for automotive paints and printing inks and as blue/cyan dyes for textiles and paper.
How do you mix phthalocyanine blue?
Step 1: Mix 1 part of Phthalo Blue (Green Shade) with 2 parts Quinacridone Magenta. The mixture will be correct when you perceive it to be the deepest blue without being described as purple. This is an approximate primary blue. Step 2: Mix 2 parts primary blue with 1 part Hansa Yellow Medium.
How is phthalocyanine blue made?
Phthalocyanine blue is prepared by heating a mixture of phthalic anhydride, urea, and copper chloride. The product is first washed in dilute caustic soda and then in dilute hydrochloric acid.
What is the difference between phthalo blue and ultramarine blue?
Side by side, ultramarine blue (left) is very different than phthalo blue (right). If we mapped each color on the color wheel, we’d see that ultramarine tilts toward the violet side of the wheel, while phthalo shifts toward the green side. Instead of traditional phthalo blue, there are several alternative pigments.
Is copper phthalocyanine toxic?
Among all of the compounds emerging upon ruby laser irradiation of copper phthalocyanine, HCN is of particular relevance due to its strong cellular toxicity. It has long been known as colorless, rapidly acting highly toxic gas (bp 26 °C)27,28.
Is pigment soluble in water?
Pigments are generally not soluble in water, oil, or other common solvents. To be applied to a material, they are first ground into a fine powder and thoroughly mixed with some liquid, called the dispersing agent or vehicle. The pigment-dispersing agent mixture is then spread on the material to be colored.
Why pigments are not soluble in water?
Chlorophyll- is a green pigment and helps in light absorption during photosynthesis. Plants and algae are in green color because of this pigment. They are insoluble in water as the long hydrocarbon tail attached to the porphyrin ring makes them fat-soluble.
