Acid Chloroacetic: Sauniuniga ma meatotino vailaau

acid Chloroacetic o acid acetic, lea o se tasi o le atoms hydrogen i le vaega methyl suia e le a atomu saoloto chlorine. E saunia e le tali acid acetic ma chlorine.

O mea o loo mata autu mo le sauniuniga o le acid acetic. e mafai foi ona maua acid Chloroacetic e hydrolysis o trichlorethylene.

maua Hydrolysis o le oloa mama chemically. Ae peitai, e aofia ai lenei metotia o le faaaogaina o mama vai malie mai ma e leai se tulaga le mama.

o loo faaaogaina acid Chloroacetic mo le mauaina o ituaiga eseese o dyes, fualaau faasaina, vaitamini ma iniseti faalafua eseese. O loo faaaogaina foi e avea o se tuufaatasi luga le malolosi (surfactants).

Chlorination o acid acetic i se auala o catalysts inorganic (faapea anhydride acetic, teio ma phosphorus) maua acid chloroacetic, o lona fua faatatau CH ₂ mata-COOH:

CH ₃ -COOH + mata ₂ ↑ → => CH ₂ mata-COOH + HCl.

meatotino faaletino

acid Chloroacetic o hygroscopic, tioata manino i ai o se tulaga faaliusuavai o 61,2 ° C ma a pupuna tulaga o 189,5 ° C. e faigofie soluble le mea (e pei o le ava malosi po o se auala aqueous, faapea foi acetone, benzene, ma tetrachloride carbon).

acid Monochloroacetic - o se mea oona ma matua matautia pe ingested lea e masani ona vaaia le oti. Ina ua uma ona fesootai ma acid chloroacetic paʻu mafua mu ogaoga e le faamalolo mo se taimi umi.

e mafai ona matauina ausa acid manavaina i totonu suiga inflammatory i le māmā, e pei foi i le tamaitusi respiratory pito i luga ma le pito i lalo.

Galulue laau tau alamanuia mo le tuuina atu o acid monochloroacetic mafatia a solia o sogisogi, rhinopharyngitis faaumiumi, peeling ma faʻamago o le paʻu.

Foi i le taimi o fegalegaleaiga faaumiumi ma mea faigata o loo matauina ai manuʻa o le epidermis paʻu, faaalia dermatitis i luga, ua, i luga ma lalo pito, i tulaga e le masani - o le tino.

acid Chloroacetic i le tino o le tagata ua liua i tiodiuksusnuyu acid, lea ua excreted i le feces ma miaga.

O le auala autu o le puipuiga mo le faaaogaina:

- matua faasaina manava puao, kesi, le asu, ma o le efuefu;

- faaaogaina pea o meafaigaluega e puipuia ai le tagata lava ia pe a faatinoina galuega e fesootai ma so o se fesootaiga ma acid (overalls impermeable, saogalemu mata tioata, seevae ma totini lima paʻu);

- i le tulaga o le manavaina i totonu po o le fesootai ma acid i le tatau ona vave saili paʻu mo tausiga tomai i le falemai aupito lata ane.

o faasalaga saogalemu theoretically aupito maualuga faatagaina o acid chloroacetic i le ea potu tuuina e uiga i se tasi mg / m ^3.

Afai felauaiga acid, e afifi i se pusa polymeric (le apa po o paelo), alafua drums ma pusa uamea. E mafai ona aveina e so o se auala o felauaiga ufitia.

E tatau ona manatua e mu gofie ma mea papa le acid monochloroacetic. O lenei mea e tele e mu gofie.
