| Siv |
1,2-Octanediol muaj ntau yam kev siv. Nws yog siv los txhim kho HPLC kev sib cais ntawm cov organic acids thiab cov hauv paus thiab los ua ke halohydrin palmitates. Tsis tas li ntawd, nws tau kawm txog nws txoj kev siv tshuaj tua kab mob pediculicide thiab tau pom tias muaj txiaj ntsig zoo tiv thaiv kab mob kab mob. |
| daim ntawv thov |
Diols pab txhawb rau cov dej solubility siab, hygroscopicity thiab reactivity nrog ntau cov organic tebchaw, ntawm feem ntau linear thiab aliphatic carbon saw. 1. Nws kuj yog siv rau hauv cov ntaub ntawv txheej, slurries, ntawv mills thiab dej ncig tshuab rau kev txuag tau zoo tiv thaiv kab mob thiab fungi. Nws yog siv los ua ib qho emollient, humectant, thiab wetting tus neeg sawv cev hauv cov khoom kho kom zoo nkauj thiab tawv nqaij. Cawv yog cov acids tsis muaj zog heev vim lawv poob H + hauv pawg hydroxyl. Cawv ua rau lub cev qhuav dej uas txhais tau hais tias tshem tawm cov dej molecule hloov los ntawm pi daim ntawv cog lus ntawm ob lub atoms carbon atoms los tsim alkenes nyob rau hauv cua sov nyob rau hauv lub xub ntiag ntawm muaj zog acids xws li hydrochloric acid los yog phosphoric acid. Thawj thiab theem nrab cawv tuaj yeem oxidized rau aldehydes thiab ketones feem. Carboxylic acids tau txais los ntawm oxidation ntawm aldehydes. Oxidation nyob rau hauv cov organic chemistry tuaj yeem suav hais tias yog qhov poob ntawm hydrogen lossis nce oxygen thiab txo kom tau hydrogen lossis poob ntawm oxygen. Tertiary alcohols tsis hnov qab muab cov khoom oxidation vim lawv tsis muaj H txuas nrog cov pa roj carbon monoxide. Cawv tau txais cov tshuaj tiv thaiv tseem ceeb hu ua nucleophilic hloov pauv uas tus neeg siv hluav taws xob hloov pauv ib pawg tawm, feem ntau conjugate bases ntawm cov acids muaj zog, ua covalent hloov ntawm qee cov atom. Ib qho ntawm cov tshuaj tiv thaiv tseem ceeb ntawm cawv yog condensation. Ethers yog tsim los ntawm condensation ntawm ob cawv los ntawm cua sov nrog sulfuric acid; cov tshuaj tiv thaiv yog ib qho ntawm lub cev qhuav dej. Yuav luag infinite esters yog tsim los ntawm condensation cov tshuaj tiv thaiv hu ua esterification ntawm carboxylic acid thiab cawv, uas ua rau dej. Cawv yog cov kuab tshuaj tseem ceeb thiab cov khoom siv tshuaj lom neeg. Cawv yog cov khoom nruab nrab rau kev tsim cov hom phiaj sib txuas, xws li tshuaj, tshuaj kho tsiaj, plasticizers, surfactants, lubricants, ore floatation agents, tshuaj tua kab, hydraulic kua, thiab detergents. |

| Siv | caprylyl glycol (1,2-Octanediol) yog ib qho emollient nrog moisturizing zog uas kuj yuav siv tau los ua kom zoo nkauj stabilizer. Thaum pom muaj nyob rau hauv ua ke nrog phenoxyethanol ob cov khoom xyaw ua hauj lwm ua ke raws li ib tug anti-microbial. |
| Siv | 1,2-Octanediol yog ib qho tshiab surfactant siv hauv kev kho mob taub hau. Kuj tseem siv hauv kev lag luam tshuaj pleev ib ce hauv kev tsim tshuaj pleev thaiv hnub gels thiab qhov muag pleev. |
| Txhais | ChEBI: Octane-1, 2-diol yog octanediol. |
| Txoj kev tsim khoom | 1, 2-octanediol tuaj yeem tau los ntawm epoxidation ntawm 1-olefin nrog cov kua qaub, cov tshuaj tiv thaiv ntawm hydrogen peroxide thiab formic acid, hydroxylation nrog dej, los yog transesterification ntawm ester uas ua los ntawm cov tshuaj tiv thaiv nrog methanol. |
| Kev piav qhia dav dav | 1. |
| Txoj kev Purification | Distil lub diol hauv vacuo thiab / lossis recrystallise nws los ntawm tsiaj ether. Cov-naphthylurethane muaj m 112-114o. [Beilstein 1 III 2217, 1 IV 2590.] S-(-)-Octane-1,2-diol [87720-91-0] kuj crystallises los ntawm tsiaj ether nrog m 35-37o and [] D -4.7o (c 35, EtOH) [Sp.th et al. Chem Ber 66 598 1933]; R-(+)-octane-1,2-diol [87720-90-9] muaj cov khoom zoo sib xws tab sis nrog kev sib hloov kho qhov muag zoo. |
