China *Corresponding author: Fax: +86 351 6111178; Tel: +86 351 60105503; E-mail: [email protected] Received: 14 March 2013; Accepted: 17 May 2013; Published online: 15 January 2014; AJC-14570 The process of acetic acid catalysis and chlorination for synthesizing chloroacetic acid can exist in not only gas phase but also liquid phase. In this paper, the gas-phase reaction mechanism of the synthesis of chloroacetic acid was studied. Due to the high concentration of acetic acid and the better reaction mass transfer in the liquid-phase reaction, the generation amount of the dichloroacetic acid was higher than that in the gas-phase reaction. Under the solution distillation, the concentration of acetyl chloride, whose boiling point is very low, was very high in the gas phase, sometimes even up to 99 %, which would cause the acetyl chloride to escape rapidly with the hydrogen chloride exhaust, so that the reaction slowed down. Therefore, series reactions occured easily in the gas-phase reaction causing the amount of the dichloroacetic acid to increase. Keywords: Gas phase, Catalysis, Chlorination, Chloroacetic acid, Acetic acid. INTRODUCTION Martikainen et al.3 summed up the reaction mechanism that was consistent with a mechanism found by Sioli according Chloroacetic acid is not only a fine chemical product but to the system condition experiment and systematic theoretical also an important intermediate in organic synthesis.

  • Chloroacetic Acid
    Chloroacetic Acid 79-11-8 Hazard Summary Exposure to chloroacetic acid is most likely to occur in the workplace. Acute (short-term) inhalation or dermal exposure may irritate or cause severe damage to the skin, eyes, respiratory tract, and mucous membranes and cause depression of the central nervous system in humans. No information is available on the chronic (long-term) effects of chloroacetic acid in humans. Damage to the respiratory tract has been observed in rodents chronically exposed to chloroacetic acid by inhalation, orally, and via gavage (experimentally placing the chemical in the stomach). EPA has not classified chloroacetic acid for potential carcinogenicity. Please Note: The main source of information for this fact sheet is EPA's Health and Environmental Effects Document for Chloroacetic Acid (2). Other secondary sources include the Hazardous Substances Data Bank (HSDB) (3), a database of summaries of peer-reviewed literature, and the Registry of Toxic Effects of Chemical Substances (RTECS) (6), a database of toxic effects that are not peer reviewed. Uses Chloroacetic acid is used in the manufacture of cellulose ethers (used mainly for drilling muds, detergents, food, and pharmaceuticals), as a post-emergence contact herbicide and defoliant, and in the manufacture of glycine and thioglycolic acid. (2) Chloroacetic acid is also used in the manufacture of various dyes, synthetic caffeine, and organic chemicals. (1,4) Sources and Potential Exposure Individuals are most likely to be exposed to chloroacetic acid in the workplace. (1) Chloroacetic acid may be released to the environment during its production and use. (2) Assessing Personal Exposure No information was located regarding the measurement of personal exposure to chloroacetic acid.

  • COUMARONE [Benzofuran]
    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein.
