Sebacicʻakika iki wailana i loko o ka wai, wailana ma ka waiʻona, a me Etera. Pure keʻokeʻo flaky nā pōaka no ka makaukau o ka polyamide, polyurethane, alkyd kēpau, kemikala lubricants, lubricant mea hoʻonui. Pīlali kēpau, hoola iho Agena Poly sebacic anhydride, a me nā meaʻala, pena, nā mea hoʻonani, a no laila, ma luna o.
Sebacicʻakika o ka mua me ka o Diosekouro ka aila a me ka mekala 'åkilikai maloo distillation loaa ma hope o ka ulu ana o kemikala ano, ua a ianoiyuaa a ulu kaʻaila N-paraffin fermentation (e nānā i ke kaʻina hana fermentation) o sebacicʻakika he hou laina. Ano, i ka hoʻomano hoʻohana 'ia ma ka hana, o Diosekouro ka aila mekala' åkilikai pāʻoihana mea i loko o ka mīkini'ātoma, o Diosekouro ka aila a me ka lye saponification naoh i 100 ℃ ua loaʻa ricinoleate a me ka glycerol. Ke ricinoleicʻakika paʻakai ua hoʻokaʻawaleʻia a me sulfuricʻakika ua hou i ka paka ricinoleicʻakika, a laila, ua lawe kumu naoh mai me ka mekala 'åkilikai, ka naoh mahana mea 260-280 DEG C a me ka haahaa puʻe paha kiʻekiʻe puʻe ua hookama. Ke naoh produces sebacicʻakika bisodium ka paʻakai, a 2-octanol a me ka hydrogen. Eia hoi, i ka sulfuricʻakika a me ka loloʻa, crystallization, maloʻo ana e loaa maemae, ka huina hua o 40% a oi.
