| Dodecanedioic acid Siv Thiab Synthesis |
| Kev piav qhia | Cov kua qaub no yog siv rau hauv kev tsim cov nylon (nylon - 6,12), polyamides, coatings, adhesives, greases, polyesters, dyestuffs, detergents, nplaim retardants, thiab fragrances. Nws yog tam sim no tsim los ntawm fermentation ntawm ntev-chain alkanes nrog ib tug tshwj xeeb hom ntawm Candida tropicalis. Nws cov monounsaturated analogue (traumatic acid) tau piav qhia hauv qab no. |
| Chemical Properties | dawb crystalline hmoov |
| Siv | Induced mutation ntawm dodecanedioic acid tsim Candida tropicalis. |
| Siv | Dodecanedioic acid yog siv los ua ib qho nruab nrab rau plasticizers, lubricants thiab adhesives. Nws kuj yog siv rau hauv cov tshuaj tua kab mob, cov txheej txheem qib siab, cov ntaub ntawv pleev xim, corrosion inhibitor thiab surfactant. Nws pom daim ntawv thov hauv engineering yas xws li nylon 612. |
| Kev npaj | Dodecanedioic acid yog npaj los ntawm cyc1ododecene (tau los ntawm butadiene) los ntawm txoj kev uas zoo nkaus li zoo rau cov siv los npaj adipic acid los ntawm benzene. Cyclododecene txo mus rau cyclododecane, uas yog oxidized ua ntej mus rau ib tug sib tov ntawm cyc1ododecanol thiab cyclododecanone thiab ces mus rau dodecanedioic acid. Dodecanedioic acid yog cov xim tsis muaj kob crystalline, mp129 degree. |
| Txhais | ChEBI: Ib qho alpha, omega-dicarboxylic acid uas yog dodecane uas cov methyl pawg tau oxidised rau cov carboxylic acids sib xws. |
| Txoj Kev Purification | Crystallize dioic acid los ntawm dej, 75% lossis 95% EtOH (solubility yog 10%), lossis glacial acetic acid. [Beilstein 2 IV 2126.] |
