Abstract

910,137. Chloro - bromo - phthalocyanines. CIBA Ltd. Nov. 16, 1960 [Nov. 20, 1959], No. 39419/60. Class 2(4). Chloro-bromo-phthalocyanines are made by reacting a metal-free or metalliferous phthalocyanine at an elevated temperature with bromine or an alkali-metal bromide in an anhydrous melt of aluminium chloride and sulphur trioxide, anhydrous sulphuric acid, sulphuric trioxide, anhydrous sulphuric acid, sulphuric acid containing sulphur trioxide or a compound of the formula R-SO 2 -Halogen where R is -OH, -OMetal, alkyl or alkoxy. The melt may also contain sodium, potassium or calcium chlorides, sodium fluoride or magnesium sulphate. Sulphur compounds of the above formula are fluorosulphonic or chlorosulphonic acids and salts and esters thereof such as sodium chlorosulphonate and' methyl sulphuric acid chloride, and methane sulphonic acid chloride. Examples are given. Specifications 818,831 and 821,629 are referred to.
