I-Hendecanoic acid (CAS#112-37-8)
Isicelo:
I-1.I-Undecanoic acid iyinhlanganisela evamile yegesi ye-chromatography yangaphakathi, i-capillary gas chromatography yangaphakathi indlela evamile yasetshenziswa ukuze kunqunywe ama-preservatives i-dehydroacetic acid, i-benzoic acid ne-sorbic acid ekudleni, izinga lokubuyisela isampula laliphakathi kuka-96% no-104%, ubudlelwano bomugqa obujwayelekile babubuhle, i-coefficient yokuhluka kokunqunywa kwesampula yayincane, i-dehydroacetic acid 0.71%, benzoic acid kwaba 0.82% kanye sorbic acid kwaba 0.62%. Ilula, iyashesha futhi inembile. Ngaphezu kwalokhu, ingasetshenziswa futhi ukucacisa okuqukethwe kwezilondolozi ezinhlobonhlobo zokudla [5-7].
2.Isetshenziswa ekukhiqizeni izithasiselo zokudla eziqukethe ama-organic acid kanye nama-medium-chain fatty acids, asetshenziselwa ukuhlola ama-medium-chain fatty acids (caprylic acid noma nonanoic acid) nama-organic acid (citric acid) anomsebenzi owengeziwe wokulwa namagciwane. ngokwelapha izinhlobo ezahlukene zama-MCFA nama-OA ahlukene, bese uqhathanisa kokubili ngesilinganiso esifanele ukuze ubenze babe nomphumela onamandla wokusebenzisana, ukuze kuqinisekiswe ukuthi umphumela we-antibacterial ungaba namandla ngesisekelo sokunciphisa umthamo we-medium-chain fatty acids nama-organic acid [8].
I-3.I-Undecanoic acid isetshenziswa ku-organic synthesis nanjenge-plastic regulator.

Ukuhogela nokungeniswa kwe-undecanoic acid kuyingozi emzimbeni womuntu. Inomphumela ocasulayo emehlweni, esikhumbeni, kulwelwesi lwamafinyila kanye nomgudu wokuphefumula ophezulu.
Ukupakisha Nokugcina:
Ipakishwe ezigubhuni ezingu-25kg/50kg.Ifakwe ezigubhuni ezingu-25kg/50kg.
Inhlanganisela ivalwa futhi igcinwe endaweni epholile, eyomile. Indawo yokugcina ikude nama-oxidants. I-Undecanoic acid powder ingabangela ukuqhuma komlilo lapho kushisa, kuvezwe elangabini elivulekile noma kuthintana ne-oxidant.
