The object of this work is to study the crystaliza -tion patterns of copper chlorids (CuCl2.2H(2)0) as influenced by extract of coffee seeds (Coffea arábica L.), variety Mundo Novo. Investigation and description are made for 16 different concentrations of the water-copper chloride-extract system, with 3 replications. The best crystallization patterns were obtained by using the filtered-mixture technique. The results indicate that concentrations between 0,5 and 1,0 g per plate of copper chloride and between 0,05 and 0,075 g per plate of extract can be recommended.Downloads
