Prospects for methyl ethyl ketone

methyl ethyl ketone is an organic solvent with excellent performance. It has the advantages of moderate volatility, strong solubility, high solid content and low viscosity. It is miscible with most hydrocarbon solvents and has no adverse effect on solid content and viscosity. It is widely used in the fields of lubricant dewaxing, coatings, adhesives, inks, tapes, pharmaceuticals and electronic components

at present, the industrial methods of hydration of n-butene to produce sec butanol mainly include indirect hydration of n-butene with sulfuric acid as catalyst and direct hydration with acid ion exchange resin or heteropoly acid as catalyst. Indirect hydration of sulfuric acid is a traditional production process, which is the main method of methyl ethyl ketone production in the world at present

in industry, catalytic dehydrogenation of SEC butanol to methyl ethyl ketone mainly includes gas-phase method and liquid-phase method. Although the liquid phase method has high selectivity and mild reaction conditions, the one-way conversion is too low, so the gas phase method is widely used at present

there are now 11 methyl ethyl ketone production enterprises in developed regions such as the United States, Western Europe and Japan. Methyl ethyl ketone produced in developed areas is mainly used in the field of coatings, accounting for more than 50% of its total consumption. In recent years, the consumption of methyl ethyl ketone in developed countries has shown a downward trend. The development of methyl ethyl ketone in developing countries will continue for some time, and its consumption will continue to grow steadily

in the United States, coating solvents are the largest consumption area of methyl ethyl ketone, but the proportion is declining. The second largest user of methyl ethyl ketone in the U.S. market is adhesive, and the dosage is on the rise. In addition, the consumption proportion of methyl ethyl ketone in tape, lubricant dewaxing and pharmaceutical and chemical intermediates remained basically unchanged. The consumption of methyl ethyl ketone in Japan has developed steadily. At present, the main consumption area of methyl ethyl ketone in Japan is solvent, accounting for 45% of the total consumption of methyl ethyl ketone, followed by printing ink and tape production

by 2000, the production capacity of methyl ethyl ketone in China was 21000 tons. In 1996, the second petroleum plant of Fushun Petrochemical Company built the first domestic methyl ethyl ketone unit, which used n-butene sulfuric acid to indirectly hydrate to produce sec butanol, and then further dehydrogenated to produce methyl ethyl ketone. Later, Jiangsu Taizhou petrochemical plant built a methyl ethyl ketone production unit using the pyrolysis raffinate C4 provided by Yangzi Petrochemical Company as raw material. China Stone protects China's excellent graphite resources and improves the deep processing level of graphite. Beijing Design Institute and Jinan Refinery have also cooperated to develop methyl ethyl ketone devices. Heilongjiang Petrochemical plant imported technology from Germany to produce methyl ethyl ketone by direct hydration and dehydrogenation of n-butene. Due to the continuous growth of domestic demand for methyl ethyl ketone and the small production in China, the market demand gap increases year by year

with the development of China's coating industry, the consumption of methyl ethyl ketone has increased year by year. In 2000, China's demand for methyl ethyl ketone reached 110000 tons, with a large gap between supply and demand

due to the small domestic production capacity of methyl ethyl ketone, most of them rely on imports. In the 1990s, the domestic consumption of methyl ethyl ketone showed an obvious upward trend, especially in recent years. From the perspective of domestic import sources, methyl ethyl ketone mainly comes from Japan, the United States, South Africa, Brazil, Singapore and other countries. The trade mode is mainly general trade, and the proportion of processing with supplied materials is decreasing year by year. The main import places of methyl ethyl ketone in China are Guangdong, Fujian, Shanghai, Jiangsu and other coastal provinces and cities. The import of thermoplastic matrix materials from Guangdong can make it possible to efficiently and deeply process semi-finished products in injection molding machines. The export volume accounts for 55% - 72% of the total domestic import

according to statistics, the demand for methyl ethyl ketone in China will still increase with the development of coatings, synthetic leather, adhesives and other industries in the future. It is estimated that the demand for methyl ethyl ketone in China will reach 150000 tons by 2005, and the market prospect is good. Therefore, in recent years, many domestic enterprises plan to expand and build methyl ethyl ketone units, and the scale is large. If they can start production on schedule, there may be a situation of excess production. It is suggested that relevant enterprises should carefully grasp investment opportunities
