Babban Tsarkakewar Glacial Acetic Acid – Mai Kara kuzari iri-iri da kuma sinadarin kore don hada kwayoyin halitta
Muhimman Fa'idodi
1. Tsarkakakken Tsabta da Kwanciyar Hankali Mai Girma:
Tsabta ≥99.5% tana tabbatar da inganci, yawan amfani da sinadarai masu yawa, wanda ya dace da sinadarai masu laushi (misali, magungunan gargajiya, kayan lu'ulu'u na ruwa).
2. Nau'in halittu:
Daraja ta Lab: Ya dace da ƙananan matakan inganta amsawa da nazarin injiniya.
Matsayin Masana'antu: Ya dace da tsarin samarwa na gwaji da ci gaba, gami da na'urorin microwave da tsarin matsi mai ƙarfi.
3. Tsaro & Dorewa:
Marufi da aka rufe (ƙirƙirar da ba ta zubewa + cikewar iskar gas mara aiki) yana hana ƙafewa da gurɓatawa, yana bin ƙa'idodin muhalli na ISO 14001.
Ana iya sake yin amfani da shi ta hanyar distillation ko hanyoyin sharar gida, wanda ke rage sharar gida da sama da kashi 70%.
4. Inganci da Farashi:
Yana maye gurbin acid mai lalata (misali, sulfuric acid) a matsayin mai ƙarfafa sinadarin acid, yana rage lalata kayan aiki.
Yana haɗaka da ruwa mai ionic don haɓaka yawan amfanin ƙasa da rage lokacin amsawa.
Aikace-aikace na yau da kullun
Magunguna:
Esterification na ibuprofen (ƙarin samar da har zuwa 98%).
Amidation na cefalexin (ƙara yawan zaɓin da kashi 20%).
Sinadaran da ke da kyau:
Haɗa ɗanɗano: Samar da esters na halitta kore (misali, isoamyl acetate, benzyl acetate).
Ma'aunin rini: Iskar shaka ta benzoic acid da aka samo daga sinadaran da ke haifar da shi (zafin amsawa ya ragu da kashi 15%).
Kimiyyar Polymer:
Haɗakar resin polyester: Samar da PET mai kyau ga muhalli ta hanyar transesterification.
Cellulose acetate: Ana amfani da shi a cikin kayan kwalliya na likitanci da kuma marufi mai lalacewa.
Sinadaran Nazarin Bayanai:
Maganin narkewar polar don shirye-shiryen lokaci na wayar hannu na HPLC.
Samfurin magani kafin amfani: Narkewar sinadarai marasa narkewa sosai (misali, alkaloids, steroids).
