M'munda wa chemistry yorganic, kufunikira kwa othandizira kuchepetsa kapena kuwononga mankhwala sikungafanane. Zina mwazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito pacholinga ichi, acetyl chloride imayikidwa chifukwa cha zinthu zake zapadera komanso zosintha. Blog iyi iperekera mawonekedwe a acetyl chloride, ntchito zake, ndi gawo lake pakuchepetsa magulu okhazikika magwiridwe antchito.
Kodi acetyl chloride ndi chiyani?
Acetyl chloride, Miculamula Ch3cocl, ndi chloride wa acid wochokera ku acetic acid. Ndi madzi opanda utoto okhala ndi fungo labwino ndipo limagwira ntchito kwambiri, makamaka ndi madzi ndi mowa. Kutengeka kumeneku kumapangitsa kuti kukhala kofunikira pamachitidwe osiyanasiyana, makamaka pa kapangidwe kazinthu zina zachilengedwe.
Gawo la acetyl chloride pakuchepetsa
Imodzi mwazomwe zimagwiritsidwa ntchitoacetyl chloridendi monga woperekera mankhwala mu umagwirira. Zimakhala zothandiza kwambiri kuchepetsera Aldehydes, matomoni ndi chlorinated phthaldes. Kutha kusankha mosankha magwiridwe antchito awa kumapangitsa acetyl chloride chida chofunikira cha akatswiri azamisala.
Chepetsani Aldeydes ndi ma ketone
Aldihydes (RCHO) ndi ma ketones (RCOR) ndi magulu ogwirira ntchito mu mankhwala opangidwa ndi anthu opangidwa. Kuchepetsa maguluwa ndikofunikira pa kaphatikizidwe ka mowa ndi zotumphukira zina.Acetyl chlorideItha kuwongolera kusandulika uku ndi ma elekitoni opereka, gulu la carbonyl kukhala gulu la hydroxyl. Izi sizongochita zokha, koma zimatha kusankha magwiridwe antchito osagwira ntchito popanda kusokoneza magulu ena mu molekyulu.
Chlorinated Naphthalenes
Chlorinated ophthalones ndi gulu lina lazinthu zomwe zimatha kuchepetsedwa pogwiritsa ntchito acetyl cloride. Izi zimagwiritsidwa ntchito kawirikawiri mu zizindikiro ndi utoto. Njira yochepetsera imatha kusintha katundu wawo, ndikuwapangitsa kukhala oyenera kugwiritsa ntchito njira zina. Pogwiritsa ntchito acety cloride, akatswiri azamicima amatha kukwaniritsa zosintha posungabe umphumphu wa kapangidwe kake.
Zabwino zogwiritsa ntchito acetyl chloride
1. Kusankha:Chimodzi mwa zabwino zambiri zogwiritsa ntchito acetyl chloride monga wopulumutsa wake ndiye kusankha kwake. Itha kulinganiza magulu ogwirira ntchito osakhudza magulu ena, kulola kusinthasintha kwa mamolekyulu achilengedwe.
2. Kuchita bwino:Mankhwala okhudzana ndi acetyl chloride amakhala okwera kwambiri, chifukwa chophatikizika kawiri nthawi. Kuchita bwino kumeneku kumakhala kopindulitsa mu mafakitale ogwiritsa ntchito nthawi ndi mtengo ndikofunikira kwambiri.
3. Kusiyanitsa:Acetyl chloride amatha kugwiritsidwa ntchito m'njira zosiyanasiyana kupatula kuchepetsedwa, kuphatikizapo maenje ndi ester synthesis. Kusintha kumeneku kumapangitsa kuti ikhale yofunika kwambiri m'bokosi la chilengedwe.
Kusamala
Ngakhaleacetyl chloridendi yokonzanso yamphamvu, iyenera kusungidwa mosamala. Ndiko kuwononga ndipo kumatha kuchititsa kuti ziwomberedwe ndi khungu kapena maso. Kuphatikiza apo, zimatulutsa hydrochloric acid ikamayamwa ndi madzi, zomwe zingakhale zowopsa. Ma protocol oyenera ndi ofunikira mukamagwira ntchito ndi masamba awa, kuphatikizapo kugwiritsa ntchito zida zoteteza (PPE) ndikugwira ntchito pamalo abwino.
Acetyl chloridendi gawo losangalatsa m'munda wa umagwirira mwamphamvu wambiri, makamaka ngati wopulumutsa alyehy, matomoni ndi chlorinated Phthaldes. Kusankha kwake, kuchita bwino, komanso kusinthasintha kumapangitsa kukhala kofunikira kwa akatswiri azama. Komabe, chitetezo nthawi zonse chimakhala chisa chachikulu mukamayendetsa zinthu zogwira ntchito zotere. Monga kafukufuku wokhazikika komanso mapulogalamu akupitilizabe kukulitsa, acetyl chloride mosakayikira apitilizabe kusewera ndi kapangidwe kazinthu zachilengedwe.
