Is phthalocyanine toxic?
Toxicity and hazards No evidence has been reported for acute toxicity or carcinogenicity of phthalocyanine compounds.
What is the molecular formula for phthalocyanine?
C32H18N8Phthalocyanine / Formula
Is phthalocyanine an organic compound?
Phthalocyanine (H2Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C8H4N2)4H2 and is of theoretical or specialized interest in chemical dyes and photoelectricity. It is composed of four isoindole units linked by a ring of nitrogen atoms.
Where does phthalocyanine come from?
In general, a crude copper phthalocyanine is produced by reacting phthalic anhydride, urea, copper/copper salt and ammonium molybdate (catalyst) in high-boiling solvent such as o-nitrotoluene, trichlorobenzene or alkyl benzenes.
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 is the short name for Phthalocyanine. It is an unusual case of the scientific name for a pigment gaining common usage and accepted by the public. The “Ph” at the beginning can look confusing to those new to the color, but it is silent so that the name is pronounced as “thalo”.
What is phthalocyanine made of?
Introduction. Phthalocyanine (Pc) molecules are macrocyclic compounds, which are composed of an inner porphyrazine ring that connects four isoindole groups giving rise to the characteristic cross-like shape (Fig. 1).
Is copper phthalocyanine toxic?
BRIGHT BLUE CRYSTALS. Decomposes on heating. This produces toxic fumes….

Is phthalocyanine blue warm or cool?
Cool blues are those with a green bias. There are many of them – Phthalo Blue, Prussian Blue, Cerulean blue, Manganese Blue, Winsor Blue and so on.
What is a substitute for phthalo blue?
Ultramarine is the best alternative because that color is also a transparent pigment with a good tinting strength. Cobalt is transparent but has a weak tinting strength, and cerulean blue is only semitransparent, also with a weak tinting strength.
Is phthalocyanine blue the same as Phthalo blue?
What color is Phthalo?
blue
Phthalo pigments are a family of blue and green synthetic organic pigments based on variants of copper phthalocyanine, a deep blue compound produced by the reaction of phthalic anhydride, urea, copper and ammonia.
Is phthalocyanine blue the same as Phthalo Blue?
Is Viridian Green the same as Phthalo Green?
Viridian is a softer, granulating and liftable version of Phthalo Green. It is lovely for florals but doesn’t have the power of phthalo green PG7, which is a very staining pigment. Phthalo Green Yellow Shade is a more neutral green. Made with PG36 it is very popular but not a colour I choose to use.
Is phthalocyanine blue the same as phthalo blue?
What is a substitute for Phthalo Green?
If granulation is desired, use Viridian (PG18) instead of Phthalo Green (PG 7) but beware that this is a less intense pigment and it is often mixed with phthalo green by manufacturers.
Is phthalocyanine green the same as Phthalo green?
It is commonly referred to as Phthalo Green and has a bright bluish green color. Copper phthalocyanine green pigment is a unique product that is essentially copper phthalocyanine blue pigment in which most of the hydrogen atoms have been replaced with chlorine atoms.
What is Phthalocyanine H2Pc?
Phthalocyanine ( H2Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C8H4N2)4H2 and is of theoretical or specialized interest in chemical dyes and photoelectricity. It is composed of four isoindole units linked by a ring of nitrogen atoms.
What are the derivatives of phthalocyanine?
There are many derivatives of the parent phthalocyanine, where either carbon atoms of the macrocycle are exchanged for nitrogen atoms or the peripheral hydrogen atoms are substituted by functional groups like halogens, hydroxyl, amine, alkyl, aryl, thiol, alkoxy and nitrosyl groups.
What is the standard state of phthalocyanine at different temperatures?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).?) Phthalocyanine ( H2Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C8H4N2)4H2 and is of theoretical or specialized interest in chemical dyes and photoelectricity.
What is the history of copper phthalocyanine?
In 1927, Swiss researchers serendipitously discovered copper phthalocyanine, copper naphthalocyanine, and copper octamethylphthalocyanine in an attempted conversion of o -dibromobenzene into phthalonitrile. They remarked on the enormous stability of these complexes but did not further characterize them.
