MorpholineMorpholine is an important fine chemical, which can be used to prepare rubber vulcanization accelerators such as NOBS, OTOS, rust inhibitors, preservatives, cleaners, scale removers, pain killers, local anesthetics, fruit preservatives, textile printing and dyeing auxiliaries, etc. It is widely used in rubber, medicine, pesticides, dyes, coatings and other fields.The production methods of morpholine mainly include diethanolamine method and diethylene glycol method.Diethanolamine process is a traditional production method. Diethanolamine raw materials needed need to be imported, and the price is expensive, the reaction yield is low, the production cost is high, and the product is no longer competitive;The diethylene glycol process is a newly developed morpholine production process in recent years. It uses diethylene glycol and liquid ammonia as raw materials. The process is simple, the conversion rate is high, and the source of diethylene glycol is sufficient. In particular, the development of morpholine in ammonia plants has the advantages of liquid ammonia and hydrogen. Two thirds of domestic existing manufacturers use this process to produce morpholine.With the rapid development of China's rubber industry, especially the tire industry, morpholine production has been stimulated and promoted.Morpholine has become a hot fine chemical product in China. Many scientific research institutes have conducted a lot of research on its synthesis technology
High content of N-methylmorpholine CAS 109-02-4The nature and use of N-methylmoline The molecular formula of N-methylmoline is, which is a colorless transparent liquid with a special amine odor. The melting point is 1 ℃, the boiling point is ℃, and the relative density is.Soluble in organic solvents, miscible with water and ethanol.N-methylmoline is a heterocyclic tertiary amine containing ether structure, which has the dual properties of tertiary amine and ether. It is an important fine chemical raw material and pharmaceutical intermediate.It is widely used in the synthesis of pesticide, bactericide, plant growth regulator and other pharmaceutical intermediates, as well as the synthesis of fine chemical products such as surfactant, lubricating oil coolant, metal rust inhibitor, fiber treatment agent, etc. It can also be used as extractant, emulsifier, corrosion inhibitor, polyurethane foam foam catalyst, etc., as well as solvent,Extractant and polyurethane coating curing agent.Among them, it is particularly important as a raw material for the production of methyloxymoline.Domestic status of N-methylmoline N-methylmoline is widely used in organic synthesis, especially in the synthesis of pesticides, medicine and other aspects.But for a long time, the domestic can not meet the requirements of p-methyl

High effective internal absorption bactericide enoylmorpholineDimethomorph is a derivative of cinnamic acid compounds, belonging to morpholine fungicides.It was first reported in France in 1988. It was used to control grape downy mildew and potato and tomato late blight. It is a new highly effective internal absorption fungicide against downy mildew fungal diseases, and has high activity against both resistant and sensitive strains of benzamide fungicides.In practical application, enoylmorpholine is another ideal fungicide to control Oomycetes diseases after metalaxyl, especially suitable for resistance control in the field where the resistance to benzamide fungicides is dominant.
