Toxicity
ACGIH: TWA 10 ppm; STEL 15 ppmOSHA: TWA 10 ppm(25 mg/m3)NIOSH: IDLH 50 ppm; TWA 10 ppm(25 mg/m3); STEL 15 ppm(37 mg/m3)
Drug Information
Recommended Personal Protective Equipment: Protective clothing should be worn when skin contact can occur. Respiratory protection is necessary when exposed to vapor. Complete eye protection is recommended; Symptoms Following Exposure: Breathing of vapors causes coughing, chest pains, and irritation of the nose and throat; may cause nausea and vomiting. Contact with skin and eyes causes burns; General Treatment for Exposure: INHALATION: Move the victim immediately to fresh air. If breathing becomes difficult, give oxygen and get medical attention immediately. INGESTION: If the victim is conscious, have him drink water or milk. Do not induce vomiting. SKIN OR EYE CONTACT: Flush immediately with lots of clean running water; wash eyes for at least 15 min. and get medical attention as quickly as possible; remove contaminated clothing; Toxicity by Inhalation (Threshold Limit Value): 10 ppm; Short-Term Exposure Limits: 40 ppm for 5 min.; Toxicity by Ingestion: LD500.5 to 5.0 g/kg (rat); Late Toxicity: No data; Vapor (Gas) Irritant Characteristics: Vapors cause moderate irritation such that workers will find high concentrations very unpleasant. Effects are temporary; Liquid or Solid Irritant Characteristics: This is a fairly severe skin irritant; may cause pain and secondary burns after a few minutes of contact; Odor Threshold: 1.0 ppm.
Ethyl 2-(Chlorosulfonyl)acetate Use and Manufacturing
Used in the manufacture of vinyl acetate monomer (VAM), this accounts for one-third of acetic acid consumption.As a food additive (condiment, ingredient) or as a preservative, it is found in Vinegar solutions, usually between 3-9% in concentration.In the production of various synthetic materials, acetic acid is a precursor and solvent for various glues and plastics such as polyvinyl acetate, cellulose acetate, nylon and dimethyl terephthalate.As an agent widely used in the manufacture of organic compounds which are constituent parts of food ingredients, various dye stuffs and perfumes, Rayon fibre, synthetic fibres and textiles, inks and dyes, soft drinks bottles, rubbers and plactics, and pesticides.In waste water treatment, acetic acid may be dosed to correct highly alkaline pH from where caustic soda has been dosed to the fluid stream.For testing blood in clinical laboratoryFor the treatment of outer ear infections from the growth of fungus and bacteria
Pharmaceutic aid (acidifying agent).
Acetic Acid is an acid produced chemically from the conversion of alcohol to acetaldehyde to acetic acid. it is the principal component of vinegar which contains not less than 4 g of acetic acid in 100 cm3 at 20°c. the approved salts include sodium acetate, calcium acetate, sodium diacetate, and calcium diacetate. it is used as a preservative, acidulant, and flavoring agent in catsup, mayonnaise, and pickles. it can be used in conjunction with leavening agents to release carbon dioxide from sodium bicarbonate.
Colorless liquid prepared by the distillation of wood or the oxidation of dilute ethyl alcohol. Acetic acid has a very pungent smell, and the vapors are flammable. When obtained in full strength (99 percent), it congeals as an ice-like solid at 16.7°C. For this reason the term glacial is also used to describe this acid. It is soluble in water, alcohol, ether, chloroform, and gelatin.Acetic acid was used as a restrainer for the physical development of calotypes, Niépceotypes, and collodion plates. Photographers also used it to retard non-image reduction of these processes by adding it to the silver nitrate solution. Acetic acid is used as a stop bath and as a solvent for gelatin.
