Abstract

The invention relates to a technology for producing nylon-11 engineering plastic by using castor oil, in particular to a method for synthesizing bromine hydride by adopting an upright burner which pertains to the technology. The method solves the problem that the purity of bromine hydride is not high in the bromine hydride synthesizing technology in the prior art of producing nylon-11 engineering plastic by castor oil. Preheated evaporating bromine of 320 DEG C and pure hydrogen, the mole ratio of which is 1 to 1.2, are sent into a combustor from the bottom of the upright burner at the same time, ignited in the combustor that is heated to 800 DEG C to start burning; after the burning is stable, heating is stopped and bromine and hydrogen are supplied constantly to produce qualified bromine hydride in the combustor continuously. The method well solves the problem that the quality of bromine hydride is low, leads to the reduction of byproduct of the bromide 100 times and greatly improves the quality of the product.

Description

Method for Synthesizing Hydrogen Bromide Using Vertical Burner technical field The invention relates to a process for producing nylon-11 engineering plastics from castor oil, in particular to a method for synthesizing hydrogen bromide by using a vertical burner belonging to the process. Background technique Polyundecamide plant engineering plastic (H[NH(CH2)10CO]nOH) is an important high-tech new material. It is an important variety of polyamide engineering plastics and an irreplaceable resin. It uses castor oil as raw material. Compared with other products, it has low density, high mechanical strength, stable performance, acid and alkali resistance, and excellent electrical insulation performance. Due to these excellent and unique properties, it is widely used in many fields such as automobile industry, electronic appliances, medical equipment, ordnance and civil industry. The existing castor oil route synthesis nylon-11 (polyundecamide) engineering plastics technology ...
