Sep 27, 2018· A new efficient method for the chemical decomposition of polyamide 6.6 by the glycolysis and amino-glycolysis processes was proposed. The glycolysis was conducted using the mass excess of ethylene glycol (EG) as a decomposing agent in the presence of a catalyst. Also, a mixture of EG and triethylenetetramine was used as another decomposing agent in the amino-glycolysis process.

ABSTRACT. Commercial nitric acid (HNO 3) and ammonia (NH 3) are mostly produced through the Ostwald process and the Haber-Bosch process, respectively.However, high energy demand and enormous greenhouse gas accompy these processes. The development of economical and green ways to synthesize HNO 3 and NH 3 is highly desirable for solving the global energy and environmental crisis.

Nitric acid (HNO3), also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68%. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid ...
Laboratory Waste Disposal Procedure Summary. Make sure the materials placed in the municipal waste are suitable for this type of disposal, especially: Do not place any liquids in the municipal waste. Do not dispose of chemical waste, including stock containers with unused product, in the municipal waste.
Aug 01, 2013· Reaction (2) has a negative temperature coefficient and is therefore favored by low temperatures. To reduce the temperature of the products from reaction (1) as quickly as possible and also to recover a large amount of heat generated by the reaction, a series of heat exchangers is placed in the process gas stream e.g. as illustrated in Fig. 7 4.These heat exchangers may be waste heat …
