  What is the chemical of 2-(2-Ethoxyethoxy)ethyl acetate? Appearance: Colorless and transparent liquid ; Assay：99%min by GC ; IR Identity: conform to standard ; HNMR： conform to standard ; carbon spectrum: conform to standard ; Water by K. F.:0.5% max or as per the customer’s request ; Loss on drying:0.5% max. or as per the customer’s request ; boiling point: 210–223°C; =============================================================================== Usage: As an environmentally friendly, low volatility solvent with excellent performance, high boiling point, high flash point, and slow evaporation rate, it is widely used in multiple industrial fields ? Coatings and paints: As a coagulant, it improves the film-forming performance of latex paint and is used in high-end coatings such as car paint, refrigerator paint, and airplane paint to achieve a high gloss surface. Printing ink: used as a solvent to regulate the fluidity and adhesion of ink. Electronics industry: used in photolithography processes as photoresist thinner, photoresist remover, IC cleaner, and photoresist buffer. Other industrial applications: Can be used as a solvent for dyes, resins, plastics, and insecticides, as well as in formulations for metal and glass surface cleaning agents ============================================================================ There are two main synthetic routes: 1. Synthesis by reacting diethylene glycol monoethyl ether (Carbitol, CAS: 111-90-0) with acetic anhydride or acetyl chloride: This is the most direct and commonly used industrial synthesis method. Starting from diethylene glycol monoethyl ether, the hydroxyl group (- OH) in its molecule undergoes esterification reaction with acetic anhydride ((CH3 CO) ? O) or acetyl chloride (CH3 COCl) to produce the target product diethylene glycol monoethyl ether acetate. The reaction conditions of this route are relatively mild and the yield is high. The synthesis efficiency reported in the literature can reach about 75%. 2. Ethylene glycol monoethyl ether (CAS: 110-80-5) reacts with ethylene oxide to produce diethylene glycol monoethyl ether, which is then acetylated: this is a two-step process. Firstly, ethylene glycol monoethyl ether undergoes an addition reaction with ethylene oxide under alkaline conditions to form diethylene glycol monoethyl ether. Subsequently, the generated diethylene glycol monoethyl ether undergoes acetylation reaction (such as reaction with acetic anhydride) to ultimately obtain diethylene glycol monoethyl ether acetate. In addition, the mention of "111-90-0 75-05-8 112-15-2" in some supplier information may suggest another potential synthetic pathway, which is to first react ethylene glycol (111-90-0) with ethanol (75-05-8) to produce diethylene glycol monoethyl ether, which is then acetylated. But the mainstream and clearly documented route still mainly follows the first one
