摘要

本文研究了a-晶型、β-晶型、ε-晶型及对溶剂稳定的a-晶型铜酞菁颜料在数种不同类型有机溶剂、水介质中的稳定性;研究了上述四种不同的晶型铜酞菁粉末试样在不同的气相介质(空气、氮气、氨气及盐酸气)中加热条件下晶型转变的临界温度及初始时间

并对试样进行了x-射线衍射分析.

Abstract

In this article

the stability of four polymorphic modifications of copper phthalocyanine(α

β-

ε- and crystallization-resistant α-CuPe) in different organ- ic solvents and aqueous mediums are studied. The transformation and stability of the four crystalline powder samples in different atmospheres (N2

air

ammonia and HCl gas) are studied by X-ray diffractometry. The critical temperature and the initiation of crystal transformation from α to β form are determined.
