Micro chemical technology is a new chemical technology created in the 21st century. Due to the miniaturization of equipment characteristic scale, compared with traditional kettle type and tubular chemical equipment, micro chemical equipment has the advantages of high transfer rate, easy direct amplification, high equipment safety, easy control and wide adaptability. It can realize the miniaturization, safety and green environmental protection of chemical reaction process.
(1) micro reactor chemical amplification and integration technology is an interdisciplinary frontier technology of modern chemical engineering, which is monopolized by developed countries represented by the United States.
⑵ nitrification is an important chemical production process, which belongs to strong exothermic process and has great potential explosion safety hazards. It is urgent to develop a new continuous and safe production process.
(3) alkane nitration, especially propane nitration, is an important basic raw material for fine chemical industry, which can derive more than 2000 derivatives. It is suitable for all walks of life in the national economy. It is monopolized by Angus company of Dow Chemical, with rich economic benefits.
Jiaxing Runbo Chemical Technology Co., Ltd. has organized the research and development of micro reactor since 2009, and used the micro reactor to develop the continuous reaction technology of propane nitrification, solve the key technology of rapid mass and heat transfer in the process of propane nitrification, and completely solve the potential safety hazards of propane nitrification. This technology is the first in China and the leading level in the world. 10t / A and 100t / a pilot scale demonstration units for propane nitrification have been built, and 600 ton pilot scale integrated technology development and optimization are under way. The research and development of this project breaks through the monopoly status of Corning company in micro chemical technology, breaks the monopoly of Dow Chemical on propane Nitration Technology and its Angus on nitration derivative market, accelerates the industrialization development process of micro chemical integrated technology in China, and promotes the fine development of chemical and material industry in China. Six patents have been applied for, namely "method for preparing nitropropane by safe gas-phase nitration (cn102079710a)", "a high-throughput micro reactor for continuous nitration of propane (cn204602159u)", "a method for separating aminobutanol (201610568112.6)", "a method for preparing 2-amino-1-butanol (201710439396.3)", "A method for preparing nitroalkanes by alkali metal catalyzed gas-phase nitration (201710439929.8)" and "a method for preparing tertiary amino alcohol compounds by one pot method (201710723743.5)".
