Ask for help: Product instructions for nitric acid, adipic acid, and dicarboxylic acid esters. Does anyone have it? If you need it urgently, thank you very much for sharing! Thanks! ! !
Nitric acid； Nitric acid [English name] nitric acid [Structure or molecular formula] HNO3 [Relative molecular weight or atomic weight] 63.01 [Density] 1.5027 (25°C) [Melting point (°C)] -42 [Boiling point (°C)] 86 [Properties] Colorless fuming liquid. General products are slightly yellow, and fuming nitric acid is a reddish-brown liquid. Irritating. [Solubility] Soluble in water. [Use] It is a strong oxidant that can passivate iron without further corrosion. Available for producing nitrogen fertilizer, aqua regia, nitrate, nitroglycerin, nitrocellulose, * * * , TNT, picric acid, etc. 【Preparation or Source】In industry, it is generally produced by nitrogen oxidation method. Laboratory can be obtained by reacting sulfuric acid with sodium nitrate. In industry, distillation is generally used for purification, and commercial products can be prepared with pure water in any proportion (usually about 65%). [Others] Splashing on the skin can cause burns and dye yellow spots. Generally slightly yellowish. Fuming nitric acid is a reddish-brown liquid that smokes violently in the air and absorbs moisture. It is unstable and decomposes when exposed to light or heat to release nitrogen dioxide. Its aqueous solution is electrically conductive. Concentrated nitric acid is a strong oxidant and can passivate aluminum. Reacts violently with many metals. Mixing concentrated nitric acid with organic matter, wood chips, etc. can cause combustion. It is highly corrosive and can burn the skin and damage mucous membranes and respiratory tract. When in contact with protein, a bright yellowish color of yellow protein is generated. Nitric acid is one of the three strongest acids in the inorganic chemical industry and has the properties of acids.
Thank you so much! ! There are also product instructions for adipic acid and dibasic acid esters. Does anyone have it? If you need it urgently, thank you very much for sharing! Thanks! ! !
Current adipic acid industry* * Are there any relevant industrial policies?
Currently, are there any relevant access standards for the petrochemical industry?
Is there any existing template for adipic acid project application report that we can refer to: handshake
