Chloroacetic acid: mmepụta na chemical Njirimara

Chloroacetic acid bu acetic acid nke bu otu n'ime umu hydrogen na mpaghara methyl ka ejiji chlorine n'efu. A na - enweta ya n'ihi mkparịta ụka nke acetic acid na chlorine.

Isi akụrụngwa maka mmepụta bụ acetic acid. A pụkwara inweta chloroacetic acid site na hydrolyzing trichlorethylene.

N'ihi hydrolysis, a na-enweta ngwaahịa dị ọcha. Otú ọ dị, usoro a na-agụnye iji dị ọcha distilled mmiri na-enweghị adịghị.

A na-eji chloroacetic acid mee ihe dị iche iche na-acha akwa ahụ, ọgwụ ọjọọ, vitamin na ụdị ọgwụgwọ ọ bụla. Ọ na-eji dị ka a elu-n'ọrụ ogige (surfactants).

Chlorination nke acetic acid na a na-ajụ nke inorganic akpali (ya bụ acetic anhydride, sọlfọ na site) nwetara chloroacetic acid, onye usoro Kra ₂ cl-COOH:

Kra ₃ -COOH + cl ₂ ↑ → => Kra ₂ cl-COOH + HCl.

Njirimara nke anụ ahụ

Chloroacetic acid bụ hygroscopic, kristal transparente na-agbaze nke 61.2 Celsius C na ebe okpukpu nke 189.5 Celsius C. Umi bụ ngwa ngwa soluble (dị ka na-aba n'anya ma ọ bụ na otu okenye na-ajụ, dị ka nke ọma dị ka acetone, benzene, na carbon tetrachloride).

Monochloroacetic acid - ihe na-egbu egbu ma dị oke egwu, na ingestion nke na-abụkarị ihe na-egbu egbu. Ọ bụrụ na akpụkpọ ahụ ya, akpụkpọ anụ chloroacetic na-ebute ọkụ ọkụ, nke na-adịghị agwọ ogologo oge.

Mgbe iku ume na acid vapors, mmetụ na-agbanwe na ngụgụ, yana na mgbago ala na ala ala, nwere ike ime.

Ndị ọrụ ụlọ ọrụ mmepụta ihe maka mmepụta nke monochloroacetic acid na-ata ahụhụ site na mmebi nke isi ísì, ụbụrụ rhinopharyngitis na-adịghị ala ala, nkwụsị na akpụkpọ anụ.

Nakwa, site na mkparịta ụka dị ogologo na mkparịta ụka dị ike, a na-ahụ ọnya anụ ahụ na-egbuke egbuke, gosipụtara dermatitis na ihu, olu, elu na akụkụ dị ala, na obere okwu - ogwe.

A na-agbanwe Chloroacetic acid n'ime ahụ mmadụ ka ọ ghọọ thiodiacetic acid, nke a na-esi n'ahụ ya pụọ na feces na mmamịrị.

Ntuziaka nke isi maka ime ihe:

- Agbochibido igbochi vapors, gas, anwuru na uzuzu;

- iji onye nchedo mgbe n'ịrụ ọrụ metụtara na bụla na kọntaktị na acid (impermeable overalls, nchekwa enyoanya, roba akpụkpọ ụkwụ na uwe);

- Ọ bụrụ na ị na-ekpuchi vapors ma ọ bụ kọntaktị acid na akpụkpọ anụ ahụ, rịọ enyemaka enyemaka nke ụlọ ọgwụ kacha nso.

Oke allowable theoretically mma ịta nke chloroacetic acid na mmepụta ụlọ ikuku bụ banyere otu mg / m ^3.

Mgbe ị na-ebufe acid ahụ, a na-etinye ya na paịlị plastik (ihe mgbochi ma ọ bụ breeze), batrị cardboard, yana ihe nchara ígwè. A na-ekwe ka ụgbọ njem site n'ụdị njem ọ bụla kpuchie.

E kwesịrị icheta na monochloroacetic acid bụ ọkụ na ihe mgbawa. Nke a dị nnọọ ọkụ.
