Hendecanoic acid (CAS#112-37-8)
Isicelo:
I-1.Undecanoic acid yinto eqhelekileyo yegesi ye-chromatography ye-compound standard yangaphakathi, i-capillary gas chromatography yangaphakathi indlela esemgangathweni yayisetyenziselwa ukumisela i-preservatives dehydroacetic acid, i-benzoic acid kunye ne-sorbic acid ekutyeni, isampuli yokubuyisela isampuli yayiphakathi kwe-96% kunye ne-104%, i Ubudlelwane bomgca obuqhelekileyo bebulungile, i-coefficient yokwahluka kokuzimisela kwesampulu yayincinci, i-dehydroacetic acid yayi. I-0.71%, i-benzoic acid yayingu-0.82% kunye ne-sorbic acid yi-0.62%. Ilula, iyakhawuleza kwaye ichanekile. Ukongeza koku, ingasetyenziselwa ukumisela umxholo weentlobo ezahlukeneyo zokugcinwa kokutya [5-7].
I-2.Isetyenziselwa ukuveliswa kwezongezo zokutya eziqulethe i-organic acids kunye ne-medium-chain fatty acids, ezisetyenziselwa ukukhuhla i-acids ephakathi kwe-chain-chain (i-caprylic acid okanye i-nonanoic acid) kunye ne-organic acids (i-citric acid) kunye nomsebenzi ongakumbi we-antibacterial. ngokunyanga iintlobo ezahlukeneyo ngee-MCFAs kunye nee-OAs ezahlukeneyo, kwaye emva koko utshatise ezo zimbini ngokomlinganiselo ofanelekileyo ukuzenza zisebenzise isiphumo esinamandla se-synergistic, ukuze kuqinisekiswe ukuba isiphumo se-antibacterial sinokuba namandla ngesiseko sokunciphisa umthamo we-medium-chain fatty acids kunye ne-organic acids [8].
I-3.Undecanoic acid isetyenziswe kwi-organic synthesis kunye nomlawuli weplastiki.

I-Undecanoic acid inhalation kunye nokungeniswa kuyingozi kumzimba womntu. Inomphumo ocaphukisayo emehlweni, ulusu, i-mucous membranes kunye nomgudu wokuphefumula ophezulu.
Ukupakisha kunye noGcino:
Ifakwe kwi-25kg / 50kg drums. Ifakwe kwi-25kg / 50kg igubu.
Ikhompawundi ivalwe kwaye igcinwe kwindawo epholileyo, eyomileyo. Indawo yokugcina ikude kwii-oxidants. I-Undecanoic acid powder inokubangela ukuvutha komlilo xa ishushu, ivelele kwidangatye elivulekileyo okanye idibene ne-oxidant.
