Physicochemical properties of nitrogen (N2)

Physicochemical Properties of Nitrogen (N2) 1. At room temperature and pressure, nitrogen is a colorless, odorless, and inert gas. Nitrogen accounts for approximately 78.1% of the air. Liquid nitrogen is also colorless and odorless, lighter than water, and does not burn in air. It is inert at room temperature but reacts with cyanides to synthesize ammonia under high temperature and pressure with a catalyst. 2. Active nitrogen can be obtained by decompression discharge. At high temperatures, it reacts with metals to form nitrides (such as Mg3N2, Cu3N2). At 1000℃, it reacts with calcium carbide to generate calcium cyanamide. 3. Slightly soluble in water, alcohol, and ether.

Introduction to Membrane Separation Technology and Applications

Membranes are materials with selective separation functions. The process of separating, purifying, and concentrating different components of a solution using the selective separation of membranes is called membrane separation. It differs from traditional filtration in that membranes can perform separation at the molecular level, and the process is physical, requiring no phase change or addition of auxiliaries. Membranes generally have pore sizes in the micrometer range. Based on their pore size (or molecular weight cutoff), membranes can be classified into microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes. Based on the material, they can be classified into inorganic and organic membranes. Inorganic membranes are mainly available at the microfiltration level and primarily consist of ceramic and metal membranes.
