Hendecanoic acid（CAS#112-37-8）
Noi:
1.Undecanoic waika mea he maʻamau kinoea chromatography i loko maʻamau pūhui, ka capillary kinoea chromatography kūloko hana maʻamau i hoʻohana 'ia e hoʻoholo i ka preservatives dehydroaceticʻakika, benzoicʻakika a me ka sorbic waika i loko o ka ai, ka hāpana hoʻihoʻi helu ma waena o 96% a me 104%, ka. He maikaʻi ka pilina laina maʻamau, he liʻiliʻi ka coefficient o ka hoʻololi ʻana o ka hoʻoholo hoʻohālike, he 0.71% ka waika dehydroacetic, ʻO ka waikawa benzoic he 0.82% a he 0.62% ka waikawa sorbic. He maʻalahi, wikiwiki a pololei. Ma waho aʻe o kēia, hiki ke hoʻohana ʻia e hoʻoholo i ka ʻike o nā preservatives like ʻole i ka meaʻai [5-7].
2. Hoʻohana ʻia ia i ka hana ʻana i nā mea hoʻohui meaʻai e loaʻa ana i nā waikawa organik a me nā ʻakika momona medium-chain, i hoʻohana ʻia no ka pale ʻana i nā ʻakika momona medium-chain (ka waikawa caprylic a i ʻole ka waikona nonanoic) a me nā waikawa organik (citric acid) me ka hana antibacterial. ma ka mālama ʻana i nā ʻano like ʻole me nā MCFA a me nā OA like ʻole, a laila hoʻohālikelike i nā mea ʻelua i kahi ratio kūpono e hoʻoikaika i ka hopena synergistic ikaika, i mea e hōʻoia ai hiki ke ikaika ka hopena antibacterial ma ke kumu o ka hoʻemi ʻana i ka nui o nā ʻakika momona medium-chain a me nā waikawa organik [8].
Hoʻohana ʻia ka 3.Undecanoic acid i ka synthesis organik a ma ke ʻano he mea hoʻoponopono plastic.
