Waikawa Chloroacetic: takanga me ngā āhuatanga matū

waikawa Chloroacetic he waikawa ahetiki, i roto i nei tetahi o nga ngota hauwai i roto i te rōpū mewaro whakakapia e te ngota māota free. Kei te rite te reira na roto i te tauhohe i waikawameha ahetiki ki māota.

Ko te matua rauemi raw mo te faaineineraa he waikawameha ahetiki. taea hoki te whiwhi Chloroacetic waikawa i tauhohenga wai o trichlorethylene.

Tauhohenga wai o te hua parakore matū whiwhi. Heoi, tā tenei tikanga te whakamahi o parakore wai māturu ki kahore he poke.

Kei te whakamahia te waikawa Chloroacetic mō te whiwhi ngā momo o waikano, taero, huaora me ngā patukīrea. Kei te whakamahia hoki te reira i rite te pūhui mata-hohe (surfactants).

Chlorination o waikawameha ahetiki i roto i te reo o kaiwhakakökï pararopi (ara anhydride ahetiki, he whanariki me te ūkuikui) whiwhi waikawa chloroacetic, tona tātai CH ₂ Cl-COOH:

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

ngā āhuatanga ōkiko

waikawa Chloroacetic he hygroscopic, karaihe mārama he ira whakakoero o 61,2 ° C me te ira koropupū o 189,5 ° C. Ko te taonga, ko te ngāwari wairewa (rite i roto i te waipiro ranei i roto i te reo wai, me te hauwaiwaro, benzene, me te waro tetrachloride).

waikawa Monochloroacetic - he taonga paitini, me te tino mōrearea ka ingested te maha kite nei te mate. I muri i whakapā ki te waikawa chloroacetic kiri ai weranga nui e kore e e whakaora mo te wa roa.

Ka taea te kite kohu waikawa inhalation huringa inflammatory i roto i te pūkahukahu, me te i roto i te wahi romahā o runga, me te raro.

Mahi otaota ahumahi mo te hanga o te waikawa monochloroacetic mamae te takahi o kakara, rhinopharyngitis ma'i, tihorenga me te maroke o te kiri.

pāpaka hoki i roto i ngā auroa ki matū pukuriri e kitea o te kiriwaho kiri, ua faaite dermatitis i runga i nga topito mata, kaki, i runga, me te raro, i roto i ngā take onge - te utumu.

Kei te tahuri waikawa Chloroacetic i roto i te tinana tangata ki tiodiuksusnuyu waikawa, excreted nei i roto i te feces me mimi.

Ko te tikanga matua o te whakatūpatotanga mō te whakamahi:

- tino rāhuitia manawa kohu, hau, paoa, me te puehu;

- te whakamahi tonu taputapu whaiaro paruru ka mahi ana mahi e pā ana ki tetahi whakapā ki te waikawa (overalls impermeable, mōwhiti haumaru, pütu rapa me karapu);

- i roto i te take o te inhalation whakapā ki te waikawa i runga i te kiri ranei kia rapu tonu mo te tiaki mohio i roto i te whare tata hauora.

Mōrahi tīkina kukū haumaru takahi o te waikawa chloroacetic i roto i te rangi production ruma ko e pā ana ki kotahi mg / m ^3.

Ki te waka waikawa, kua tākai reira i roto i te ipu polymeric (te ipu oko ranei), pahu muka me ipu maitai. Ka taea te kawea e tetahi tikanga o te waka hipoki.

Kia mahara te reira e te mea pūkākā, ka pakū te waikawa monochloroacetic. Tenei taonga ko tino pūkākā.
