For the purpose of antirust oil (grease) products, used for copper and copper alloy gas phase corrosion inhibitor in circulating water treatment agent, antifreeze, photographic antifogging agent, polymer stabilizers, plant growth regulators, lubricating oil additives, UV absorbent. This product can also be used in conjunction with a variety of scale inhibitor, biocide.

The utility model is widely used for corrosion inhibition of copper and silver equipment. It can also be used for the preparation of anti fogging, anti fogging agent and the preparation of vapor phase inhibitor.

Use in the electroplating for surface purification of silver, copper, zinc, a color change. BTA and copper atoms form covalent bonds and coordination bonds, which are mutually linked into chain like polymers, and the multilayer protective film is formed on the surface of copper and copper. Lead, cast iron, nickel, zinc and other metal materials have the same effect. BTA can be combined with a variety of corrosion inhibitors to improve the corrosion inhibition effect. Also with a variety of scale inhibitor, biocide use, especially for the closed circulating cooling water system corrosion effect is very good, in the glycol and water by car, added to the coating of BTA can protect the function of volatile material. BTA is a good product for UV absorbers, UV sensitive can play a stabilizing role, such as preventing diazo dye fade, BTA paper, fabric, film, metal coins and other sheet products can prevent discoloration. In the process of machining, the BTA can be added to the grinding oil and cutting oil, so that the copper parts can not be changed. The product can also be used as an analytical reagent, and can be used for the selective determination of silver, copper and zinc with ammonia and two amino acid and acetic acid. Can also be used as a photographic antifogging agent and organic synthesis intermediates.

It is also used as an analytical reagent and photographic antifogging agent for organic synthesis

Use of lubricating oil additives, metal reducing agents, extreme pressure additives, bacteria and oxidation inhibitors, as antioxidants in internal combustion engine oils

The production method is derived from the reaction of three - and sodium nitrite. The two benzene amine was dissolved in the water at the temperature of 50 DEG C, and then added with glacial acetic acid, and the temperature was reduced to about 5 DEG C. The reaction gradually become dark green, the temperature rise to 70-80 DEG C, the solution becomes orange, in room temperature for 2h, cooling, filtering out crystallization, water washing, and drying to obtain the crude product, the crude distillation, collecting 201-204 C (2.0kPa) fractions, and benzene can be re crystallization, melting point 96-97 the product yield of about 80% DEG C. It has been reported that sodium nitrite was used to treat the condensation wastewater of carbendazim, and the by-product was three.

The production method is to add a certain amount of water in the reaction kettle, heating to 50 DEG C. Then add 1 mol of benzene to the amine, with a of acetic acid of 2.01 mol, stirring and cooling to a temperature of about 0 DEG C, with a drop of 1 mol sodium nitrite. The temperature gradually increased to 73 DEG C, and the reaction was 2h. Stay overnight. The filter cake is washed two times, dried, crushed and sieved.
