Alkyl-phenol Plant  is a group of compounds produced by phenol alkylation. The term is generally used to indicate the commercial value of propofol, butyl phenol, pentyl phenol, heptyl phenol, octyl phenol, nonylphenol, decyl phenol and related long chain alkyl phenol (LCAP). Methyl phenol, dimethyl phenol and ethylphenol are also a kind of alkyl phenols, but they are usually not included in alkyl phenols. Alkyl phenol is an estrogenic hormone. It's also known as endocrine disruptor. Long chain alkylphenol is widely used in detergents, as well as additives in fuel, lubricating oil and polymers, and one of the raw materials of phenolic resin. We can provide professional  Alkyl Phenol Production Process . If there is any need, please feel free to contact us.

We have a professional  Methyl Acetate Plant , where we can provide  Methyl Acetate Production . The following is a brief introduction to the preparation process. Acetic acid and methanol were synthesized with sulfuric acid as catalyst to produce methyl acetate crude products, and then dehydrated with calcium chloride, neutralization of sodium carbonate and the finished product. Refining method: the main impurities are free acetic acid and methanol because of easy hydrolysis of methyl acetate. The existence of methanol can be seen from its solubility in water. At room temperature, methyl acetate dissolved in water by 24%. If 1% methanol exists, it can be mixed with water. When refined, 85mL acetic anhydride was added in 1000mL of methyl acetate, and then fractionated after 6 hours. Acid impurities can be vibrated with anhydrous potassium carbonate and then distilled. The methanol can also be removed by acetyl chlorination. High purity methyl acetate can be washed with salt water,

This product is a colourless liquid which has a fruity ester odour. It is often used as a solvent in the production of polymers, resins, oils and cellulose. This item is extremely flammable with a flash point of 18º C along with also a flammability rating of 3. It is highly miscible with all common organic solvents (alcohols, ketones, glycols, esters) but just marginally miscibility in water. The most Frequent method for manufacturing  Isobutyl Acetate  is via the esterification of isobutyl alcohol and acetic acid which are heated in the presence of a solid acid. We are  Isobutyl Acetate Plant Manufacturer , and more information,welcome to contatc us :info@slchemtech.com.

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 wastewater. After the r

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.

Technology Introduction of Formaldehyde Plant SL TEC Formaldehyde Plant SL TEC  has close to ten years experience in formaldehyde production technology based on silver contact process(or silver catalyzed process).

Sheets Combined Corrugated Structured Packing Each periodic ripple of the Zupak is composed of more than four intermittent planar graphic sheets located on four planes. The lateral projection shape is two interlaced corrugated lines. The uniform parallelogram channel on the filler has completely replaced the circular holes on the regular structured packing. It can not only save 8.5% of the material, but also increase the specific surface area of the corresponding quantity. The packing has the advantages of low pressure, large flux, good transversal air permeability and high separation ability. It can be widely used in the industrial fields of distillation, absorption, extraction, heat exchange, washing and so on. Compared to corresponding Mellapak packing, Zupak  has advantages as follows: The specific area increases by around 10%; The porosity opening rate increases by 30-40%; The separation efficiency increases by about 10%; The throughout increases 20%; The pressure
