The chemical industry is a pillar industry of my country's national economy, and it is also one of the industries with high energy consumption and heavy pollution. For example, levulinic acid has a wide range of chemical production needs and can be used in various fields such as pesticides, resins, solvents, medicines, spices, inks, rubber and plastic additives, lubricant additives, surfactants, antifreeze, preservatives, etc. Therefore, green synthesis of levulinic acid is of great significance.
Facing many problems such as resource shortage, energy shortage and environmental pressure, the chemical industry needs to integrate the concept of green development throughout the entire production process to promote energy conservation and emission reduction, clean production, circular economy and low-carbon development.
In particular, we must rely on scientific and technological progress to strengthen engineering technology innovation, establish an engineering technology system that is compatible with resource-saving and environment-friendly industries, promote industrial optimization and upgrading, vigorously adjust the industrial structure, improve product quality, increase the proportion of high-end chemical products, and reduce energy consumption. consumption and material consumption, and achieve sustainable development through green, recycling, and low-carbon technological innovation.
For example, levulinic acid has a wide range of chemical production needs and can be used in various fields such as pesticides, resins, solvents, medicines, spices, inks, rubber and plastic additives, lubricant additives, surfactants, antifreeze, preservatives, etc. Therefore, green synthesis of levulinic acid is of great significance. Levulinic acid is a white flaky crystal, flammable, hygroscopic, easily soluble in water, alcohol, and ether organic solvents. It hardly decomposes when distilled under normal pressure. If heated for a long time, it will lose water and become unsaturated γ- lactone.
Levulinic acid is the basic raw material for the synthesis of various light chemical products. It has extensive use value in organic synthesis, industry, agriculture, and pharmaceutical industries, and chlorinated levulinic acid can be used as a bacteriostatic agent for industrial circulating water. In agriculture, the amine salt of chlorinated levulinic acid can be used as a herbicide and defoliant. In medicine, anti-inflammatory drugs and intravenous injections can be produced from levulinic acid through deep hydrolysis of starch, glucose and cellulose raw materials.
Because of its high reactivity, it can be made into various new polymer materials and chemical products, and has been widely promoted and applied. This product is of low toxicity. It is packed, stored and transported in plastic barrels and reinforced with wooden boxes. It is stored in a cool, dry and ventilated place away from fire sources. It is stored and transported according to the regulations on flammable chemicals.
