PIGMENT
Phthalocyanine Pigments
These pigments are the most produced organic pigment in the world. They cover the colour from greenish blue to reddish blue & blueish green to yellowish green
They are produce by reacting metal salt with nitrogen source compound & phthalic acid derivative
They show good solvent & migration resistance, good , light, heat, chemical & weather fastness
Commercial application cover a whole range of product
SYNTHESIS of Phthalocyanine Pigment
Copper Phthalocyanine Blue
BLUE PIGMENT CuPc (Copper Phthalocyanine) Blue pigment CuPc is one of the most stable pigments towards light, temperature and chemicals and hence, combined with its attractive colors, this pigment is widely used in many applications such as in paints water & solvent based paints including automotive paints), in water & solvent based inks, in textiles and in plastics with temperature of operations up to 350 C.
In industry, this pigment is produced in two stages The first stage is the preparation of the Blue Crude CuPc while the 2nd is the Pigmentation of crude CuPc ie the reduction of particle size of Crude CuPc.
Copper Phthalocyanine Blue
CRUDE CuPc Blue
Crude CuPc is commonly prepared by reacting copper chloride urea, phthalic anhydride, catalyst with solvent.
• CuCl + 12 H2NCONH2 + 4 C6H4 (CO)2O CuPc + NH3 + CO2 + H2O + NH4Cl (produced in Malaysia)
• Structure of CuPc Yield 90%
Production of Crude CuPc
Phthalic anhydride , urea , and trichlorobenzene and CuCl with the ratio of 4:12:5:1 are mixed in 1000 L of vessel equipped with an oil bath and stirrer: 2% weight of CuCl of ammonium molybdate are then added. The mixture are heated up slowly within 1 hour to 200 C . Gas evolution mostly CO2 and some NH3 with formation of phthalimide begins at 130 C. Formation of CuPc begins at 160-170 C, with simultaneous released of CO and NH3. After stirring at 200-205 C for 1 hour, formation of the pigment is complete.
The Phthalocyanine is filtered of ; washed with hot trichlorobenzene at 50 C, methanol and hot water; and dried.
The yield of CuPc is max 90%

PROBLEMS OF MANUFACTURING CRUDE CuPc
1. YieldThe yield of reaction is max 90% based on copper chloride used (see List of Patents). There are therefore about 10 % of the reagents used are disposed as waste.
2.. Environmental EffectMost of the waste of the production of crude CuPc (11,000 tons/yr) is precipitated using Na2S and then is buried underground

Pigmentation by Sulfuric Acid
Production of alpha –CuPc Pigment from crude CuPcCrude CuPc is added quickly to conc. H2SO4 (96%) with ratio of 5-9:1 , and the temp is allowed to rise to 50 C . The suspension is stirred overnight.
When the phthalocyanine is completely dissolved , the suspension is sprayed into 35000 L of water at 70 C, and the temp is allowed to rise to 85 C – 90 C. The precipitated pigment is filtered off in a filter press and washed until acid free.
The presscake is then mixed with water, and the remaining acid is neutralized with K2CO3 and ammonia. After addtion of Lorol sulfonate the suspension is heated for 1 h until a clear filtrate is obtained.
After filtration of the suspension, the presscake is washed with hot water and homogenized with sufficient water to give a 20% paste, which is past 3-5 times thro a disintegrator (3000 rpm).
Pigmentation by Grinding
Production of Beta-CuPc Pigment from Crude CuPcIn a kneader , crude CuPc is ground for 8 hours with NaCl with the ratio 4:1 and with the aid of Diethylene Glycol (DEG).
Then this paste is boiled in water 4x of the total weight and filtered using filter press to remove water/soluble substances. Washing with hot water is continued until no water soluble substances can be found.
The presscake is then dried at 70 C – 75 C or using spin flash drier. A intensive greenish blue beta-CuPC is obtained.
Copper Phthalocyanine Green
1 The most common organic green pigments are Phthalocyanine green
2 The Phthalogreens are made by halogenating CuPc blue to produce mixtures of CuPc in which many of the 16 hydrogen atoms on CuPc have been replaced by chlorine or mixture of chlorine and bromine atoms
3 The pigments vary from blue green to yellow green depending on the ratios of bromine to chlorine
4 The yellowish green are obtained with nine to ten bromine atoms per molecule
5 The Phthalogreens are economical and have good light fastness
Copper Phthalocyanine Green
MARKET DEMAND for Copper Phthalocyanine World production of this product is over 110,000 tons/year while the gap between the world demand and the supply according to Business Analyst for Asahi Songwon Colors Ltd for 2011 is 19,000 tons / year.
PRODUCTION COUNTRIES Crude CuPc was used to be produced in Japan, Europe and America but now it has been shifted to mainly China and India due to lower labor cost and also mainly as the waste regulations of these countries are not strictly followed.

CALCULATIONS
Material Weight used for 1 MT CuPc
Unit Price / MT Cost
CuCl 191 kg $ 6,565 $ 1,254.00
Phthalic Anhydride 1143 kg $ 1,500 $ 1,714.50

Catalyst 2.60 kg $ 24,000 $ 62.40
Total Cost CuPc $ 3,517.90 / MT
Profit
The profit for the manufacturers of this product would increase tremendously by using this new process. For example, a medium size manufacturer that produces 5000 MT CuPc/ year with the FOB price of the low quality CuPc is $5.76/kg, the expenses are as follow:
If the cost of raw materials ($3.52), packaging ($0.04) and energy ($0.44) to be $4.00/kg then to produce 5000 MT = $20m
And if the cost for machinery is assumed to be $1m so a 5 yrs depreciation= $0.2m/yr
And if the number of workers employed is 100 with salary assumed to be $600/month each, so salary = $0.72m/yr
Profit
Then Profit :
(5000 MT x $5.76) - $20m - $0.2m - $0.72m + (10% x 5000 MT x $5.76) = $7.88m + $2.88m$10.76m/yr (before depreciation of building, Interest & Tax)
The profit should be more than this as the saving cost for the waste treatment should be added to this amount.
