Mucochloric acid is a white powder with a sour odor that is used in the manufacture of crop protection products.
Extraction and presentation
Mucochloric acid can be prepared by chlorination of butynediol in aqueous acidic medium (eg. Hydrochloric acid or sulfuric acid are recovered).
Annual production in the EU was around 1000 to 5000 tonnes in 2000. This makes it one of the chemical substances that are produced in large quantities (" High Production Volume Chemical ", HPVC) and for which the Organization for Economic Cooperation and Development (OECD) collects data on possible dangers (" Screening Information Dataset ", SIDS).
Mucochloric acid is mainly used as an intermediate in the manufacture of the pesticides Chloridazon and Norflurazon .
