Molecular formula : MW : CAS :
nature : solid state (crystalline) material without passing through the liquid directly into a gaseous phenomena. When sublimation heat absorption. Different material in different temperature distillation. For example, ice and snow at low temperature will be raised, naphthalene, camphor, solid carbon dioxide at room temperature will be raised, iodine, sulfur and mercury chloride (mercuric chloride) in the heating will be sublimated. Easy stems from the material can be purified into law. For example, naphthalene, camphor, iodine, sulfur, mercury chloride.
