In order to achieve the goal of building the first chemical large-scale non-standard equipment manufacturing base in Shanxi, Fengxi Group Chemical Equipment Co., Ltd., through independent research and development and joint research institutes, has overcome a number of technical difficulties. Among them, alumina evaporation equipment manufacturing technology has been highly evaluated by foreign experts.
The company and Northeastern University jointly digested and absorbed French technology, and produced the complete set of equipment for the evaporation section of the 1 million tons alumina project of Shanxi Luneng Yuanping. The company's first super-built 4.5-m-meter, 5100-m heat-exchange area and 150-ton-heavy domestic first super. Large tubular heat exchangers form a manufacturing technology with independent intellectual property rights.
In addition, the company also cooperated with Sichuan General Chemical Technology Co., Ltd. to solve the problems of forming, pairing, welding and heat treatment of the equivalent expansion coefficient of the 13MnMoNiNbR duplex stainless steel, and overcame the technical difficulties in the manufacture of the methanol synthesis tower; in conjunction with Tianliang Chemical Design Institute, Designed and developed key equipment such as heating furnace for coke oven gas to methanol, oxygen-enriched preheating furnace, etc.; meanwhile, it overcomes all-position CNC pulsed tungsten-arc welding technology for tubes/tubesheets, making the heat exchanger tubes and U-tubes. The automatic connection of the nozzle and the tube plate to achieve automatic argon arc welding. The development and application of these new technologies have increased the technical content of the equipment and have played a key role in further expanding the market and improving the competitiveness of enterprises.

Butyl acetate is mainly used as a solvent and a chemical reagent. This product is irritating to the eye and the mucous membrane of the upper respiratory tract. There is an anesthetic effect. It can cause dry skin and can be absorbed through a complete skin. In addition, it also has some harm to the environment.
Application
1. N-Butyl acetate is used as solvent in coating, lacquer, printing ink, adhesive, leatherroid, nitrocellulose, etc.
2. it is the solvent of some cosetics, acting as medium boiling solvent of nail polishes to dissolve the epithelium forming agents, like, nitrocellulose, acrylate and alkyd resins. It also can be used to prepare the remover of nail agents. It is often mixed with Ethyl Acetate while in use.
3. it is also applied to prepare perfume, it appears in the recipes of apricot, banana, pear and pineapple essences.
4. in petroleum refining ands pharmaceutical industry, it is used as extractant, especially the extractant of some antibiotics.
5. N-Butyl acetate is an azeotrope former with good ability to carry water, it is ofter used to condense some weak solution to reduce energy consumption.
6. N-Butyl acetate also can be used as analytical reagent verify thalium, stannum and tungsten, and determine molybdenum and rthenium.
