The Main Use of Sec-butyl Acetate

图片
Sec-butyl acetate  can be used as a solvent, the solubility of sec-butyl acetate (SBA) is similar to n-butyl acetate and isobutyl acetate. In the coating formulations, it can be widely replaced with n-butyl acetate and isobutyl acetate. In metallic flash paint,  sec-butyl acetate  can be used to dissolve cellulose acetate butyrate to produce 15% to 20% solution.  Acetyl acetate has good solubility in many substances, it can be used as a solvent for making nitrocellulose paint, acrylic paint, polyurethane paint, etc. These lacquers can be used as aircraft wing paint, artificial leather paint, automobile paint and so on. Acetyl acetate can also be used for the manufacture of celluloid products, rubber, safety glass, coated paper, patent leather and other products. It can also be used as a volatile solvent in printing inks for applications such as offset printing. It can also be used as a quick-drying agent for photographic materials.

Application of Urea Formaldehyde (UF) Glue

The polymer obtained by reacting urea with formaldehyde is known as  urea formaldehyde glue , referred to as UF. Urea and 37% formaldehyde aqueous solution in the acid or alkali catalyzed can be polycondensation of linear urea-formaldehyde oligomers, the industry to alkali as a catalyst, to ensure that the resin can be cured. The first reaction produces mono- and dimethylol urea, and then the hydroxymethyl group is further condensed with the amino group to give a soluble resin which, if catalyzed by acid, easily results in a gel.  The product must be stored under neutral conditions. Linear urea-formaldehyde resin to ammonium chloride as a curing agent can be cured at room temperature. Urea-formaldehyde resin is mainly used in the manufacture of molded plastic, the manufacture of daily necessities and electrical parts, but also for sheet adhesives, paper and fabric slurries, Tiemian Ban, architectural decorative panels. Because of its light and easy to color, products are of...

The Top Ten Uses of Sec-butyl Acetate

图片
Acetyl acetate is colorless, flammable liquid with a fruit flavor, it has excellent ability to dissolve into a variety of synthetic resin and natural resin. The boiling point is lower than n-butyl acetate, faster evaporation. There are two methods for the production of  sec-butyl acetate : alcohol esterification and olefin-acetic acid addition. The use of sec-butyl acetate is also widespread. (1) used as paint solvent and ink solvent, widely used as nitro paint, acrylic paint, polyurethane paint, polyester paint, amino paint, epoxy paint and other solvents. (2) as a solvent for the synthetic resin manufacturing process. (3) as a solvent for the curing agent manufacturing process. (4) it is used as a diluent. (5) used as a cleaning agent: sec-butyl acetate can be used for washing water washing, washing water, washing plate. (6) used for the pharmaceutical industry: sec-butyl acetate can be used as antibiotics, hormones, vitamins in the production process of extractant; its vola...

Future Market Prospects of Sec-butyl Acetate

图片
At present, the market commonly used solvents are n-butyl acetate, ethyl acetate, toluene and xylene. Butyl acetate is more widely used, but the price is too high; ethyl acetate volatilizes too fast, resulting in its use is limited; Toluene and xylene are highly toxic to humans and the environment. For the  sec-butyl acetate , its price is competitive compared with the solvent, and also has the advantages of strong dissolving performance, moderate evaporation rate, high extraction yield, little toxicity and little residue. It can save costs, can improve product quality, reduce the human body poisoning, reduce atmospheric pollution. Compared with n-butyl, the price is a big advantage. In recent years, due to the global demand for environmental protection increasingly stringent, low-cost sour butyl acetate is to meet this trend. According to the current demand and export situation, China's sec-butyl acetate production gap is increasing, there is still much room for the development...

MTBE Application

图片
If you belong to a large refinery, or petroleum blending companies, you will need to MTBE, MTBE application is more and more wide, also often used in engineering company, EPC contractor and chemical engineering consultants, especially big manufacturers of methanol and mixed C-4 raw material. If you need to produce MTBE, you must use  MTBE Plant . MTBE can be used as the petroleum additive and pyrolysis produces high purity isobutylene, can also be as reaction solvents, extraction solvents and chromatography liquid because of its stability.
