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

I-Heptanedic acid, eyaziwa ngokuba yi-stearic acid okanye i-caprylic acid, i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-heptanetic acid:

Umgangatho:
- Ukubonakala: I-Heptaneic acid yikristale engenambala eqinileyo okanye umgubo omhlophe.
- Ukunyibilika: I-Heptalaic acid iyanyibilika kwi-alcohol kunye ne-ether solvents, ayinyibiliki emanzini.

Sebenzisa:
- I-Heptaneric acid, njenge-organic compound, ineendlela ezahlukeneyo zokusetyenziswa kwishishini.

Indlela:
- I-Heptalaic acid inokufumaneka nge-acid-catalyzed oxidation yeoli. Ngokuqhelekileyo, i-heptalaic acid ikhutshwa kwi-coconut okanye kwioli yesundu.

Ulwazi ngoKhuseleko:
- I-asidi ye-Heptanedic ngokuqhelekileyo ithathwa njengekhompawundi ekhuselekileyo. Ayicaphukisi kangako ulusu kodwa iyacaphukisa emehlweni. Xa usebenzisa okanye uphatha i-heptanoic acid, kufuneka kuthathwe unonophelo ukuze ugweme ukudibanisa ngokuthe ngqo kwesikhumba kunye namehlo, kunye nokugcina indawo enomoya. Kwimeko yoqhagamshelwano ngengozi, hlambulula ngokukhawuleza ngamanzi kwaye udibane nodokotela.
- I-Heptanedic acid ayizinzile kwaye inokutshisa xa ibonakaliswe kumaqondo aphezulu okanye amadangatye avulekileyo. Xa ugcina kwaye usebenzisa, kufuneka ugcinwe kude nemithombo yomlilo kunye namaqondo okushisa aphezulu, kwaye ugweme ukudibanisa ne-oxidants kunye ne-acids eqinile.
- I-Heptanedioic acid kufuneka igcinwe kwisikhongozelo esingangeni moya kwindawo epholileyo, eyomileyo kunye nengena umoya.
