No neutralization step
The salt goes straight into the reaction, so you skip dosing caustic into MCA and handling the heat it releases.
Хлорацетат натрия (SMCA, sodium monochloroacetate) is the pre-neutralized form of MCA, used where a process needs the chloroacetate group without adding caustic first — betaine surfactants, CMC and carboxymethylated intermediates. SUNCHEM supplies SMCA in 25 кг-мешки с сертификатом подлинности партии на каждую отправку.
SMCA carries the same reactive –CH₂Cl group as monochloroacetic acid, already neutralized as the sodium salt. Charging the salt avoids the heat and extra water of neutralizing MCA in the reactor, which is why it is the usual feed for cocamidopropyl betaine and other amphoteric surfactants, and an option for CMC and carboxymethyl starch.
Buyers usually check assay, влага, sodium chloride and the pH of a solution: together they decide the salt load and the residual chloroacetate in the finished product.
The salt goes straight into the reaction, so you skip dosing caustic into MCA and handling the heat it releases.
Quaternizing fatty amidoamines and tertiary amines with SMCA is the established route to cocamidopropyl betaine and lauryl betaine.
Send your incoming-inspection sheet — assay, влага, NaCl, pH — and we quote against it, с пакетным сертификатом подлинности для каждого лота.

Where SMCA is used, и что необходимо подтвердить перед переключением источника питания.
Reacted with fatty amidoamines such as cocamidopropyl dimethylamine, or with alkyl dimethylamines, to make cocamidopropyl betaine (CAPB), lauryl betaine and related amphoterics for shampoos, body wash and detergents.
Used as the etherifying agent for carboxymethyl cellulose and carboxymethyl starch where the plant doses the sodium salt instead of MCA.
A carboxymethylating agent for phenols, amines and thiols in pesticide, pharmaceutical and dye-intermediate synthesis, and in other industrial processes.

|---|---|---|---|---|
| SMCA | 3926-62-3 | C₂H₂ClNaO₂ | 116.48 | Pre-neutralized; common in betaine and CMC plants that dose the salt |
| МКА | 79-11-8 | C₂H₃ClO₂ | 94.50 | Acid form; most CMC, herbicide and pharma routes |
Both deliver the same –CH₂COOH group. Choose by how your process is set up, and confirm with a trial.
25 кг мешки. Tell us your pallet pattern and labeling requirements with the order.
Храните сумки закрытыми в прохладном месте., dry place; SMCA takes up moisture. Store away from strong acids and oxidizers and follow the SDS for handling.
Classified as toxic for transport (И 2659, Сорт 6.1, PG III); it ships with dangerous-goods documents.
Бетаин, CMC or an intermediate: each sets different limits for assay, влага и хлорид. Tell us which one and the grade you make.
Put assay, влага, NaCl and solution pH on the same COA template as your incoming inspection, so offers are compared like for like.
SMCA ships as UN 2659, Сорт 6.1. Согласен упаковка, labeling and the destination port early so the booking does not delay the first order.
