1-Tetradecanol Siv Thiab Synthesis
Kev piav qhia 1-Tetradecanol yog ib hom kev haus cawv ncaj nraim. Nws yog feem ntau siv los ua cov khoom xyaw hauv cov tshuaj pleev ib ce xws li cov tshuaj nplaum txias vim nws cov khoom emollient. Nws tseem tuaj yeem siv los ua qhov nruab nrab thaum lub sijhawm tsim khoom ntawm qee cov organic tebchaw xws li surfactants. Qee cov kev tshawb fawb tau pom tias nws tuaj yeem cuam tshuam qhov kev ua kom endothelial thiab txo cov ntaub so ntswg teb rau cytokines, muaj peev xwm kho cov kab mob raws li kev tshawb fawb ntawm luav. Nws kuj tseem ua haujlwm rau kev tsim cov tshuaj kub-tswj tshuaj tso tawm raws li cov ntaub ntawv hloov pauv theem.

Chemical Properties dawb tsawg melting khoom los yog flakes
Chemical Properties Myristyl cawv tshwm sim raws li ib tug dawb crystalline khoom nrog ib tug waxy tsw. Kuj tau tshaj tawm tias opaque leaflets los yog crystals los ntawm ethanol.
Siv myristyl cawv yog ib qho emollient feem ntau siv hauv tes cream, txias cream, thiab tshuaj pleev ib ce kom lawv zoo nkauj, velvety. Cov peev txheej qhia tias nws yog me me comedogenic thiab muaj peev xwm ua rau khaus.
Siv 1-Tetradecanol yog siv los ua cov khoom siv hauv cov tshuaj pleev ib ce xws li cov tshuaj nplaum txias. Nws yog ib qho active intermediate nyob rau hauv cov tshuaj synthesis ntawm sulfated cawv. Nws kuj yog ua hauj lwm nyob rau hauv fabrication ntawm kub-tswj tshuaj tso tawm system raws li theem-hloov cov ntaub ntawv. Nws ua lub luag haujlwm tseem ceeb hauv kev sau cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
Siv Raws li emollient rau cov cream txias, thiab lwm yam, kuj ua rau cov dej cawv sulfated uas nws cov ntsev ntsev yog siv los ua "wtter" hauv textiles.
Txhais ChEBI: {{0}}Tetradecanol yog ib tug ntev-chaw fatty cawv uas yog tetradecane nyob rau hauv uas ib tug ntawm cov terminal methyl hydrogens yog hloov los ntawm ib pawg hydroxy Nws yog ib tug ntev-chain thawj fatty cawv, fatty cawv 14 :0 thiab thawj cawv.
Txoj kev tsim khoom Myristyl cawv muaj nyob rau hauv spermaceti wax thiab phev roj, thiab tej zaum yuav raug synthesized los ntawm sodium txo cov fatty acid esters los yog txo cov fatty acids los ntawm lithium aluminium hydride. Nws tuaj yeem tsim los ntawm acetaldehyde thiab dimethylamine.
Kev npaj 1-Tetradecanol yog npaj los ntawm lub taub hau roj ntawm Sperm Whale ntawm cov kua qaub thiab cov ester.
Synthesis Reference (cov) Phau ntawv Journal of Organic Chemistry, 35, p. Xyoo 1210, 1970DOI:10.1021/j00829a089
Kev piav qhia dav dav Cov kua dej tsis muaj xim tsis muaj xim (rhuab) nrog cov ntxhiab tsw ntxhiab tsw ntxhiab. Solidifies thiab ntab saum dej.
Cua & Dej Reactions Insoluble hauv dej.
Reactivity Profile 1-Tetradecanol yog cawv. Cov nplaim hluav taws kub hnyiab thiab / lossis cov pa phem yog tsim los ntawm kev sib xyaw ntawm cov cawv nrog alkali hlau, nitrides, thiab muaj zog txo cov neeg ua haujlwm. Lawv hnov ​​​​mob nrog oxoacids thiab carboxylic acids los tsim esters ntxiv rau dej. Oxidizing agents hloov lawv mus rau aldehydes lossis ketones. Cawv muaj ob qho tib si tsis muaj zog acid thiab tsis muaj zog hauv paus cwj pwm. Lawv tuaj yeem pib ua cov polymerization ntawm isocyanates thiab epoxides.
Health Hazard Tsawg toxicity. Overexposure ua rau qee lub hauv paus paj hlwb kev nyuaj siab. Kev sib cuag ntawm daim tawv nqaij ntev ua rau tawv nqaij khaus.
Flammability thiab Explosibility Tsis cais
Kev siv tshuaj Myristyl cawv yog siv nyob rau hauv qhov ncauj, parenteral, thiab tshuaj pleev tshuaj formulations. Nws tau raug soj ntsuam raws li kev nkag mus rau hauv melatonin transdermal thaj ua rau thaj hauv nas.
Myristyl cawv kuj tau raug soj ntsuam raws li ib tug bilayer stabilizer nyob rau hauv niosome formulations uas muaj ketorolac tromethamine, thiab zidovudine.Niosomes uas muaj myristyl cawv pom ib tug considerably txo qis tus nqi ntawm ketorolac tromethamine tshaj cov uas muaj cov cholesterol.Qhov no kuj tau soj ntsuam nrog lub zidovudine formulation.
Kev nyab xeeb Myristyl cawv yog siv nyob rau hauv qhov ncauj parenteral, thiab tshuaj pleev xim formulations. Daim ntawv ntshiab ntawm myristyl cawv yog tshuaj lom me me los ntawm kev noj thiab tej zaum yuav ua rau carcinogenic; kev sim cov ntaub ntawv tumorigenic muaj.Nws kuj yog tib neeg daim tawv nqaij irritant. Hauv kev tshawb fawb tsiaj ntawm cov tawv nqaij permeation txhim kho cov nyhuv ntawm saturated fatty alcohols, myristyl cawv pom muaj qhov qis dua thaum piv nrog decanol, undecanol, lossis lauryl cawv tab sis ua rau tawv nqaij ntau dua. cawv 10% petrolatum yuav tsum tsis txhob nqa tawm vim muaj kev cuam tshuam tsis zoo; Yog li kev siv qis dua ntawm myristyl cawv rau cov kev sim no (5% petrolatum) tau pom zoo.Myristyl cawv tau cuam tshuam nrog qee cov lus ceeb toom ntawm kev tsis haum tshuaj tiv thaiv.(8,9) Ib nrab-rau-mob erythema thiab nruab nrab edema tau pom. thaum 75 mg yog siv rau tib neeg daim tawv nqaij sib nrug ntawm peb koob tshuaj tshaj 72 teev.
LD50(Lavbit, tawv nqaij): 7.1 g / kg
LD50(rat, qhov ncauj): 33.0 g/kg
khaws cia Cov khoom siv loj yuav tsum tau muab cia rau hauv lub thawv kaw kom zoo hauv qhov chaw txias, qhuav.
Txoj kev Purification Crystallize cawv los ntawm aqueous EtOH. Nws kuj tau purified los ntawm cheeb tsam melting. [Beilstein 1 IV 1864.]
Kev tsis sib haum xeeb Myristyl cawv yog combustible thaum raug tshav kub los yog nplaim taws. Nws tuaj yeem cuam tshuam nrog cov khoom siv oxidizing. Thaum rhuab mus rau decomposition, nws emissions pa luam yeeb thiab irritating fumes.
Txoj Cai Tswjfwm Muaj nyob rau hauv FDA Inactive Ingredients Database (lub qhov ncauj ntsiav tshuaj: sustained-tso tawm; thiab tshuaj pleev ib ce: cream, lotion, suspension). Muaj nyob rau hauv nonparenteral (tshuaj pleev xim) formulations muaj ntawv tso cai nyob rau hauv UK.
