1.Dab tsi yog DMSO?
Dimethylsulfoxide, DMSO luv luv, yog cov organic compound nrog cov khoom tshwj xeeb. Nws pib los ntawm cov tshuaj tiv thaiv ntawm methanol thiab sulfur dioxide thiab tau los ntawm dehydrogenation. Raws li kev tswj hwm nruj, DMSO tau siv dav hauv ntau qhov chaw, suav nrog chemistry, tshuaj, kev ua liaj ua teb, thiab lwm yam.
Lub cev muaj zog ntawm dimethyl sulfoxide?
Dimethyl sulfoxide (DMSO) yog sulfur-muaj cov organic compound nrog molecular mis C2H6OS. Nws yog cov kua uas tsis muaj xim thiab tsis muaj ntxhiab tsw pob tshab ntawm chav tsev kub. Nws yog hygroscopic thiab flammable kua. Nws muaj cov yam ntxwv ntawm siab polarity, siab kub taw tes, zoo thermal stability, aprotic thiab miscible nrog dej. Nws tuaj yeem yaj nyob rau hauv feem ntau cov organic tshuaj xws li ethanol, propanol, benzene thiab chloroform, thiab hu ua "universal hnyav". Cua sov nyob rau hauv lub xub ntiag ntawm acid yuav tsim me me ntawm methyl mercaptan, formaldehyde, dimethyl sulfide, methanesulfonic acid thiab lwm yam tebchaw. Nws muaj qhov tshwm sim decomposition ntawm qhov kub thiab txias, reacts hnyav nrog chlorine, thiab kub hnyiab hauv huab cua nrog lub teeb xiav nplaim. Nws tuaj yeem siv ua cov kuab tshuaj organic, cov tshuaj tiv thaiv nruab nrab thiab cov organic synthesis nruab nrab. Nws kuj tseem siv tau los ua dyeing hnyav, dye remover, dyeing carrier rau hluavtaws fibers, thiab absorbent rau recovering acetylene thiab sulfur dioxide.
Dab tsi yog cov haujlwm thiab cov teebmeem ntawm DMSO?
Hauv thaj chaw ntawm chemistry, DMSO ua lub luag haujlwm tseem ceeb. Nws yog cov kuab tshuaj zoo heev uas tuaj yeem siv los ua kom yaj ntau cov organic sib txuas los pab txhawb cov tshuaj lom neeg. Tsis tas li ntawd, DMSO kuj muaj cov tshuaj antioxidant, tiv thaiv kev laus, thiab txhawb cov metabolism. Nws yog ib qho muaj zog dawb radical scavenger uas tiv thaiv cov hlwb los ntawm kev puas tsuaj oxidative. Nyob rau tib lub sijhawm, DMSO tuaj yeem txhawb nqa cov metabolism hauv cell, txhawb kev tsim hluav taws xob, thiab txhim kho lub cev muaj zog.
Tsis tas li ntawd xwb, DMSO kuj muaj qhov pom tseeb los tiv thaiv kev qaug zog. Kev tshawb fawb qhia tau hais tias kev siv DMSO ua ntej lossis thaum lub sijhawm qoj ib ce tuaj yeem pab cov neeg ncaws pob txo kev qaug zog thiab txhim kho kev ua haujlwm. Cov nqaij ntshiv ua rau qaug zog thiab puas thaum lub sij hawm siv zog ua haujlwm siab lossis ua haujlwm ntev. DMSO tuaj yeem tiv thaiv cov leeg los ntawm kev puas tsuaj dawb radical thaum txhawb cov leeg nqaij rov qab, yog li txo qhov qaug zog.
Txoj kev khaws cia
1. Cov khoom no yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw txias, qhuav kom deb ntawm lub teeb.
2. Cov khoom no yog ntim rau hauv cov thawv txhuas, cov thawv yas lossis cov iav fwj. Khaws rau hauv qhov chaw txias, qhov cua thiab qhuav, thiab khaws cia thiab thauj raws li cov kev cai rau cov khoom siv hluav taws xob thiab tshuaj lom.
