Sodium Chloroacetate (C₂H₂ClNaO₂, CAS 3926‑62‑3) is produced predominantly via the neutralization of chloroacetic acid with sodium carbonate:
2 CH₂ClCOOH + Na₂CO₃ → 2 CH₂ClCOONa + H₂O + CO₂ cdhfinechemical.com+3highmountainco.com+3hpvchemicals.oecd.org+3assets.thermofisher.com+7en.wikipedia.org+7highmountainco.com+7.
This process yields high‑purity SMCA, avoiding the over‑alkalinization issues sometimes found with sodium hydroxide. The resulting product is isolated as white, crystalline powder, subsequently washed and dried for commercial distribution.
A primary application of SMCA is in synthesizing Carboxymethyl Cellulose (CMC). SMCA acts as the alkylating agent in the etherification of alkaline cellulose, producing water-soluble CMC used extensively in food, papier, textiles, and detergents .
Studies reveal that varying SMCA dosage during synthesis—e.g., using 5–9 g SMCA per 5 g cellulose—affects the yield and degree of substitution, with optimal reaction conditions reported at ~7 g SMCA for highest CMC yield (~66%) pmc.ncbi.nlm.nih.gov+5researchgate.net+5thescipub.com+5.
Beyond CMC, SMCA is key in producing aryl‑hydroxy‑acetic herbicide precursors (like dimethoate) and various agrochemicals climatiq.io. It serves as a building block for dye, pigment, polymer additives, and shampoo surfactants via thioglycolic acid and long‑chain betaine synthesis researchgate.net+4climatiq.io+4sciencedirect.com+4.
SMCA is widely used in organic and medicinal chemistry research. According to Wikipedia, it’s a favored reagent in the Organic Syntheses series for introducing the –CH₂CO₂⁻ group and for heterocycle synthesis, cyanoacetate production, and glycolic acid generation en.wikipedia.org.
