Ethyl Acetate Production Technology

图片
Today We briefly introduce the  Ethyl Acetate Production Technology . Ethyl acetate was prepared by using salt dehydration technology and acid as catalyst, acetic acid and ethanol esterification. The quality of ethyl acetate is in conformity with GB/ t3728-2007 standard of ethyl acetate. The  Ethyl Acetate Production Process  includes: ingredients, esterification, phase separation, dehydration, refinement, recovery and so on. Acetic acid and ethanol mixed in certain proportion into esterification kettle, and then to add sulfuric acid catalyst for esterification reaction into esterification kettle, a product of the reaction after entering the esterification tower, ethyl acetate and water in the vapor phase is entered into the phase splitter overhead condenser cooling after crude ester phase. The crude ester was obtained by dehydration tower system and distillation column system. At the same time, the recovery tower system can recycle the ester and alcohol in wastewate...

The Application of Iso-butyl Acetate

图片
Iso Butyl Acetate has great solvency traits for polymers, resins, oils, cellulose and readily thinned with aliphatic hydrocarbons. It's principally utilized in the paints and coatings business for wood varnishes, architectural coatings, printing inks and adhesives. It may replace n-butyl acetate if a coat needs to dry faster. It's also widely utilised in aerosol sprays, thinners, sealants, cleaners, odor, cosmetics and individual care-products. The primary end consumer market of the item is paints, coatings, cleaning and cosmetics businesses. We have professional  Iso-butyl Acetate Plant,  and more information about  Iso-butyl Acetate Manufacturing Process , welcome to contact us:info@slchemtech.com.

Introduction of Iso-butyl Acetate Manufacturing Process

图片
Today we explain the  Iso-butyl Acetate Manufacturing Process . First,the acetic acid, isobutanol, cyclohexane, and catalyst are added to the esterification reactor in proportion, the stirring is started, and the temperature is slowly increased by jacketed steam, the esterification is continued for 1 hour, and the water and the azeotrope are continuously distilled. After the condenser is condensed, it enters the separator, the upper oil layer returns to the esterification reactor, and the lower water layer is discarded. The resulting reactants were transferred to storage tanks, the resulting reactants were cooled, the reaction liquids in the storage tanks were filtered and transferred to a neutralization scrubber, neutralized to a pH of 7.0 with a 5% strength sodium carbonate solution, and stirred half Hours, after standing, stratified and distilled, the crude ester was washed again with 20-30 water to obtain the initial product. After washing with water, dehydration was conduct...

Introduction of 1,3-dioxolane Production Process

图片
Today we briefly introduce the  1,3-dioxolane Production Process. 1, 3-dioxane is an excellent organic solvent, widely used for oil and fat solvents, extractants, electrolytic solvents of lithium batteries, pharmaceutical intermediates, etc. In addition, it can be used as raw material for silk finishing agent and sealant. Technological advantages: 1. The use of concentrated formaldehyde rather than polyoxymethylene as raw materials saves the drying of polyformaldehyde and thus reduces equipment investment; 2. Use solid acid catalyst, reduce the requirement of equipment material, and save investment.

Technical Operation of Hydrogen Peroxide Technology

图片
There are several methods for hydrogen peroxide production,The following is a brief introduction to the operation of  Hydrogen Peroxide Technology . Closed operation, comprehensive ventilation. Operators must be specially trained to strictly observe operating procedures. It is recommended that the operator wear a self-absorption filter respirator (full cover), wear polyethylene protective clothing, and wear neoprene rubber gloves. Keep away from fire and heat sources. Smoking is forbidden in the workplace. Stay away from flammable and combustible materials. Prevent steam from leaking into the workplace air. Avoid contact with reducing agent and active metal powder. Light loading and unloading to prevent damage of packaging and container. Equipped with corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may have a residue. We are professional  Hydrogen Peroxide Technology Provider , welcome to contact us if t...

Introduction of POM Production Technology

图片
We've got the pleasure to publish you hereby a short technical info regarding  POM Production Technology . The tech of Polyoxymethylene manufacturing is complicated one and belongs to so called "high tech" processes. Trusted industrial processes used for production of Polyoxymethylene worldwide. For getting a top quality final Solution, monomers utilized for Polymerization must be of high purity. This necessitates application of particular chemical technology operations in gaseous, liquid and solid condition. Polyoxymethylene (POM) resins are significant engineering resins utilized in industrial, transport,agricultural, building and customer markets. Additionally, these resins show great lubricity properties under a vast array of ecological conditions of moisture and warmth,fantastic fatigue resistance, a low coefficient of friction and springiness.

The Production Technology of Methyl Acetate

图片
Methyl Acetate  is an important organic chemical raw material, which can be used to synthesize acetic anhydride, acetamide, methyl methacrylate and vinyl acetate, etc., and methyl acetate is not a qualified organic pollutant, it is also an environmental organic solvent. The  Methyl Acetate Production  is made by substituting cationic resin solid acid instead of traditional sulfuric acid as catalyst, which can not only reduce the side reaction, but also reduce the corrosion resistance level of the equipment. Solid acid can last up to three years with less pollution.

Storage Considerations of MMA

图片
Methyl methacrylate is an organic compound, also known as MMA, referred to as methyl ester. Is an important chemical raw material, is the production of transparent plastic polymethyl methacrylate (PMMA) monomer. Flammable, strong irritating odor, moderately toxic, reproductive toxic and teratogenic, should avoid long-term exposure. Storage considerations of  MMA Technology In general, inhibitors are added to the goods. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep away from light. The temperature should not exceed 37°C. The packaging requires a seal and must not come into contact with air. Should be stored separately with oxidants, acids, alkalis, halogens, etc. Avoid mixing. Not suitable for large-scale storage or long-term storage. Use explosion-proof lighting and ventilation facilities. Do not use mechanical equipment and tools that are prone to sparks. Storage areas should be equipped with spill emergency treatment equipment and suitab...
