I-Pimelic acid(CAS#111-16-0) Ulwazi

I-Heptanedic acid, eyaziwa nangokuthi i-stearic acid noma i-caprylic acid, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-heptanetic acid:

Ikhwalithi:
- Ukubukeka: I-Heptaneic acid iyi-crystalline eqinile engenambala noma impushana emhlophe.
- Ukunyibilika: I-Heptalaic acid iyancibilika otshwaleni nasezincibilini ze-ether, ayincibiliki emanzini.

Sebenzisa:
- I-Heptaneric acid, njenge-organic compound, inokusetshenziswa okuhlukahlukene embonini.

Indlela:
- I-Heptalaic acid ingatholwa nge-acid-catalyzed oxidation yamafutha. Ngokuvamile, i-heptalaic acid ikhishwa kukhukhunathi noma emafutheni esundu.

Ulwazi Lokuphepha:
- I-Heptanedic acid ngokuvamile ibhekwa njengenhlanganisela ephephile. Ayicasuli kakhulu esikhumbeni kodwa iyacasula emehlweni. Uma usebenzisa noma uphatha i-heptanoic acid, kufanele kuqashelwe ukugwema ukuthintana ngqo nesikhumba namehlo, nokugcina indawo enomoya omuhle. Uma kwenzeka ukuthintana ngengozi, hlambulula ngokushesha ngamanzi bese ubonana nodokotela.
- I-Heptanedic acid ayizinzile futhi ingasha lapho ibhekene nezinga lokushisa eliphezulu noma amalangabi avulekile. Lapho ugcina futhi usebenzisa, kufanele ugcinwe kude nemithombo yomlilo namazinga okushisa aphezulu, futhi ugweme ukuthintana nama-oxidants nama-asidi aqinile.
- I-Heptanedioic acid kufanele igcinwe esitsheni esingangeni moya endaweni epholile, eyomile futhi engenawo umoya.
