Reaction of compound 1 with monochloroacetic acid
(1: 2 by mole) in refluxing ethanolic sodium hydroxide afforded the [alpha]-amino acid 2.
(+.) This solution also contained (in order of diminishing proportion) parachlorophenol, orthochlorophenol, monochloroacetic acid
, 2,6-dichlorophenol, phenol, and 2,4,6-trichlorophenol.
Hayes' patented NOCC-forming process treats chitin with heat and a caustic chemical such as lye or sodium hydroxide, then reacts the product it forms with monochloroacetic acid
. The Canadian government already has approved NOCC's use as a preservative film for apples that will be washed and peeled before use--about one-third of Canada's apple market.
Key projects include an expansion and upgrade of Nouryon's organic peroxides facility in Mahad, which is close to completion, as well as a new monochloroacetic acid
plant in Gujarat.
While the World Health Organization (WHO) has stipulated the maximum contaminant levels (MCL) for monochloroacetic acid, dichloroacetic acid, and trichloroacetic as 20, 50, and 200 [micro]g/L, respectively , the sum of concentrations of HAAs should not be greater than 60 [micro]g/L according to the United States Environmental Protection Agency (USEPA) .
Analytical grade standard mixture of six haloacetic acids containing monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), trichloroacetic acid (TCAA), monobromoacetic acid (MBAA), dibromoacetic acid (DBAA), and bromochloroacetic acid (BCAA) (2000 [micro]g/mL each in methyl tert-butyl ether (MTBE)) was purchased from Supelco (Supelco Park, PA, USA).
Monochloroacetic acid (MCA): Monochloroacetic acid (MCA) is a colorless crystalline substance with a molecular weight 94.50 (Toshina et al., 2004).
Toxicokinetics of monochloroacetic acid: a whole- body autoradiography study.
- Action against the Commission's decision of 17 February 2005,a fining Akzo Nobel, Hoechst and Atofina (Elf subsidiary now known as Arkema) for operating a cartel from 1984 to 1999 in the market for monochloroacetic acid
THE EUROPEAN Commission has fined three chemical companies Euro 216.91 million for operating a cartel in monochloroacetic acid
production; it makes detergents and thickens cosmetics.
The mobile phase was made with pyrogen-free water and contained monochloroacetic acid
(14.14 g/L), sodium hydroxide (4.675 g/L), octanesulfonic acid disodium salt (0.3 g/L), ethylenediaminetetraacetic acid (0.25 g/L), acetonitrile (3.5%), and tetrahydrofuran (1.4%).
AkzoNobel (Euronext: AKZA) has expanded the capacity of its plant for the manufacture of monochloroacetic acid
(MCA) in China.
