The Uses of Isobutyl Acetate

图片
Isobutyl Acetate  has great solvency traits for polymers, resins, oils, cellulose and easily thinned with aliphatic hydrocarbons. It can replace n-butyl acetate if a coating needs to dry quicker. It's also widely utilized in aerosol sprays, thinners, sealants, cleaners, odor, makeup and individual care-products. The main end user market of the item is paints, coatings, cosmetics and cleaning businesses. We are  Isobutyl Acetate Plant Manufacturer  and more information, welcome to contact us:info@slchemtech.com.

Do You Know the Chemical Properties of Methyl Acetate?

It is easy to hydrolyze in methyl acetate, and it can hydrolyze to produce acetic acid by hydrolysis at normal temperature. When heated, it is decomposed into acetaldehyde and formaldehyde, which can be further decomposed into methane, carbon monoxide and hydrogen. Halogens, especially iodine, have a catalytic effect on decomposition. In the presence of nickel, will be heated, methyl acetate decomposition does not occur under 150 ℃, more than 150 ℃ is decomposed into methane, carbon monoxide and water. When heated with air, the catalysts of copper, silver, molybdenum and other metals are decomposed into formaldehyde and acetic acid. Methyl acetate is decomposed into methanol, acetone, diacetyl, ethane, methane, hydrogen, carbon monoxide and carbon dioxide. Chloroacetic acetate was produced by reacting with chlorine under light. In the presence of sodium methoxide and methyl acetate in 57 ~ 80 ℃ by condensation, methyl acetoacetate is generated. Methyl acetate with certain salts, such ...

Do You Know Alkyl-phenol Plant ?

图片
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.

Do You Know the Preparation of Methyl Acetate ?

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 sal...
