Ethyl acetate is a widely used low-toxicity, fast-drying, and strong-solubility organic solvent. The core appears in the six major industries of paint and ink, food, medicine, adhesives, daily chemicals, and organic synthesis. It is also a commonly used reagent in laboratories, electronic cleaning, and other fields.
Coatings: Used as a solvent/diluent for nitro paints, PU paints, acrylic paints, wood paints, and automotive refinish paints to adjust viscosity, assist in leveling, and quickly dry film formation to improve gloss.
Ink: Core solvent for offset, gravure, flexo, and food packaging inks, suitable for high-speed printing to ensure color development and dryness.
Artificial Leather/Linoleum/Plastic Coating: Dissolved resin, coloring, for artificial leather, linoleum coloring, plastic surface coating.
Food flavor: GB 2760 allows use, simulates pineapple/pear fragrance, and is used to enhance the flavor of beverages, candies, ice cream, baking, and alcohol (an important aroma ingredient of Baijiu).
Extracts: extract natural flavors, caffeine, vegetable oils, and food active ingredients.
Food Packaging: For formulations of food contact grade inks and adhesives.
Drug extraction/purification: extraction and purification of penicillin, erythromycin, vitamins, active ingredients of traditional Chinese medicine, and alkaloids.
Medicinal solvents: solvents for oral liquids, tinctures, syrups, mouthwashes; solvents for pharmaceutical coatings, tablet excipients.
Laboratory analysis: chromatographic (TLC/HPLC) elution, reaction solvent, standard formulation.
Adhesives: polyurethane, neoprene, pressure sensitive adhesive, hot melt adhesive solvents for packaging, footwear, construction, stationery.
Industrial cleaning: cleaning agents for PCBs, precision instruments, molds, glasses; paint remover, dry cleaning stain remover.
Civil: Main solvent for nail polish and nail polish.
Fragrance/Essence: Solvents and setting additives to enhance aroma diffusion.
Cosmetics: nail polish, nail polish wash, skin care products, shampoo solvents and fragrance enhancers.
Intermediates: Synthesis of ethyl acetoacetate, other esters, dyes, fragrances, pharmaceutical/pesticide intermediates.
Reaction solvent: universal solvent for organic synthesis such as esterification, condensation, and transesterification.
Electronics/Semiconductors: Precision cleaning, photoresist dilution, board cleaning.
Printing/Office: Copier nitrofibre inks, printing consumables solvents.
Laboratory: Standard solvents for extraction, recrystallization, chromatography, organic synthesis.
The "K Filter" VOCs recovery unit (KF unit) provided by Cordier Environment is a dedicated equipment for the recovery of organic solvents such as ethyl acetate.
Adsorption material: Activated carbon fiber (ACF) from Japan Toyo Spinning is used. Compared with granular activated carbon, it has the characteristics of large specific surface area, fast adsorption/desorption speed and high adsorption capacity.
Process principle: The exhaust gas passes through the adsorption tank equipped with activated carbon fibers, and ethyl acetate is adsorbed. After the adsorption is saturated, water vapor is used for desorption. After the desorbed high-concentration gas is condensed and separated from oil and water, the liquid ethyl acetate is recovered.
The performance table in the document shows that the KF unit can treat ethyl acetate waste gas from the film compounding industry with a treatment efficiency of 97.0%, reducing the inlet concentration from 1000 ppm to 30 ppm at the outlet.
The document states that non-water-soluble VOCs, such as ethyl acetate, can be efficiently recovered and reused through a separation unit.
High-quality recovery: fast desorption, low solvent thermal decomposition, high purity of recovered ethyl acetate (sample data shows purity> 99.8%), can be directly recycled for production.
Safe and reliable: The process has no open flame, adopts atmospheric pressure design, and has high safety. Steam desorption itself also has a firefighting effect.
Economic and environmental protection: While solving the problem of environmental protection standards, recycling solvents can generate economic benefits and reduce production costs. Compared with the combustion method, there is no secondary emission of carbon dioxide, which is more in line with the concept of carbon neutrality.
Wide range of applications: suitable for exhaust gases with a concentration range of about 10 to 10,000 ppm.
In the domestic performance, many customers who use this technology to treat ethyl acetate, such as Huangshan Yongxin, Kunshan Jiapu, etc., have been put into operation early and the technology is mature.
