Product Details

n-Butyl Alcohol is a colorless, flammable liquid characterized by a strong alcoholic odor and a high refractive index. It burns with a bright, luminous flame. This compound is incompatible with strong acids, powerful oxidizing agents, aluminum, acid chlorides, acid anhydrides, copper, and copper alloys. n-Butyl alcohol is widely used in a variety of industrial applications.

It is mainly used as a solvent in the manufacture of paints, varnishes, synthetic resins, gums, pharmaceuticals, vegetable oils, dyes, and alkaloids. It also plays an important role in producing artificial leather, rubber, plastic cements, shellac, raincoats, perfumes, and photographic films, making it a valuable chemical across a wide range of industries.

Acrylic acid and its derivatives, particularly its esters, have a wide range of applications in various industries, including the following:

Warp Sizing Agents: Sizing agents formulated from acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, and ammonium polyacrylate are easier to remove during desizing than polyvinyl alcohol-based sizing agents. They also help reduce starch consumption.
Adhesives: Copolymer emulsions derived from acrylic acid, methyl acrylate, ethyl acrylate, and 2-ethylhexyl acrylate can be used as adhesives for electrostatic flocking. These adhesives provide excellent durability and a pleasant feel.
Water-Based Thickeners: High-molecular-weight powders obtained from acrylic acid and ethyl acrylate copolymers serve as thickening agents, particularly in oilfield applications.
Coatings for Coated Paper: Quaternary copolymer emulsions composed of acrylic acid, butyl acrylate, 2-ethylhexyl acrylate, and styrene are used in coated paper applications. They offer good color retention without yellowing, deliver superior printing performance, and prevent sticking to rollers. These emulsions outperform styrene-butadiene latex and can be used as a substitute for casein.
Polyacrylates: Acrylic acid can be used to produce various polyacrylate salts, including ammonium, sodium, potassium, aluminum, and nickel salts. These materials function as high-molecular-weight additives in a variety of applications, such as coagulants, water treatment agents, dispersants, thickeners, food preservatives, acid- and alkali-resistant drying agents, and softening agents.
