Product Parameters
Basic Properties
Physical Properties:
· Appearance: Colorless transparent liquid with pungent odor
· Melting Point: <-70°C
· Boiling Point: 145-146°C
· Density: 0.890-0.895 g/cm³ (20°C)
· Solubility: Reacts vigorously with water; miscible with ethanol, ether, acetone and most organic solvents
· Refractive Index: 1.390 - 1.392 (20°C)Chemical Properties:
· Key chemical characteristic: Highly moisture-sensitive, prone to hydrolysis
· Hydrolysis: HC(OC₂H₅)₃ + H₂O → HCOOC₂H₅ + 2C₂H₅OH
· Can undergo exchange reactions with alcohols to form mixed orthoesters
· Serves as an ethylating agent and a formyl equivalent, widely used in the synthesis of heterocyclic compounds (e.g., pyridines, pyrimidines)
· Used in the synthesis of enol ethers, vinyl ethers, and dyes
· Reacts with Grignard reagents to form aldehydes
Main Applications
Pharmaceutical Industry: Used as a key intermediate in the synthesis of various antibiotics (e.g., chloramphenicol), antimalarials, anxiolytics, and vitamins.
Agrochemical Synthesis: Used in the production of high-efficiency insecticides, fungicides, and herbicides (e.g., imidacloprid and other pyridine-based pesticides).
Dye Industry: Serves as an important intermediate for the synthesis of cyanine dyes and other various dyes.
Organic Synthesis: Used for the synthesis of enol ethers and vinyl ethers; acts as a protecting group for aldehydes and alcohols; serves as a formyl source.
Other Fields: Used in fragrance synthesis and as a specialty solvent. Used as a crosslinking agent in polymer chemistry.
Safety Precautions
Health Hazards:
· Causes severe irritation to skin, eyes and respiratory tract
· Inhalation of vapor may cause coughing, sore throat, shortness of breath, and central nervous system depression (dizziness, headache)
· Harmful if swallowed; may cause severe irritation and damage to the digestive tract
· Hydrolysis products (ethanol and ethyl formate) also possess certain toxicity and irritancyHandling Protection:
· Must be handled in a dry, well-ventilated area. Strictly prevent contact with water or moisture.
· Wear chemical safety goggles, chemical-resistant gloves and protective clothing
· Use respiratory protection effective against organic vapors
· Strictly avoid contact with skin, eyes and clothing
· Do not eat, drink or smoke in work areaStorage & Transportation:
· Store in a cool, dry, well-ventilated, explosion-proof area. Keep containers tightly sealed.
· Preferably seal under an inert atmosphere (e.g., dry nitrogen) to prevent hydrolysis and deterioration
· Keep away from heat, sparks, open flames and hot surfaces
· Store separately from strong oxidizers, strong acids, strong bases, water and moisture
· Containers must be properly grounded to prevent static accumulation
· Packaging must be absolutely moisture-proof (galvanized iron or epoxy-lined steel drums recommended)Fire Fighting:
· Flammable liquid, flash point ~30°C (closed cup)
· Vapor can form explosive mixture with air
· Use dry powder, CO2, or alcohol-resistant foam to extinguish fire
· Do NOT use water as it will cause a vigorous reaction and may spread the fire
· Firefighters must wear self-contained breathing apparatus and full protective gear
