Daim ntawv thov
1. Tetramethylthiourea feem ntau yog siv los ua ib qho zoo sulfur qhov chaw thiab reagent nyob rau hauv cov organic synthesis, yooj yim rau stereospecific deoxygenation ntawm cyanoepoxides los tsim alkenyl nitriles nrog siab diastereopurity. Nws kuj tseem ua haujlwm tseem ceeb hauv ib qho tshiab, thiol-dawb organocatalytic raws tu qauv rau kev sib txuas ntawm thioethers los ntawm aryl chlorides thiab cawv nyob rau hauv cov mob me me photochemical.
2. Tetramethylthiourea CAS 2782-91-4 yog ua haujlwm los ntawm cov roj hmab compounding tus neeg sawv cev thiab cov accelerator rau acrylate adhesives. Nws kuj tseem pom daim ntawv thov hauv kev nce cov photosensitivity ntawm photothermographic (PTG) cov ntaub ntawv.
3. Cov ntawv thov ntawm Tetramethylthiourea kuj suav nrog nws siv los ua ib lub tsev thaiv hauv kev tshawb fawb tshuaj, xws li hauv kev tsim thiab kev sib txuas ntawm cov tshiab benzisoselenazolones (BISAs) tshawb xyuas raws li muaj peev xwm c-Met inhibitors rau kev kho mob qog noj ntshav.
Cia thiab ceev faj
1. Khaws Tetramethylthiourea nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, thiab zoo - qhov cua, tiv thaiv los ntawm lub teeb thiab noo noo. Kev pom zoo cia kub sib txawv ntawm lub tub yees (2-8 degree) mus rau qhov chaw txias, tsaus nti hauv qab 15 degree, thiab nws yuav tsum tau khaws cia kom deb ntawm oxidizing cov neeg ua haujlwm thiab cov ntaub ntawv tsis sib xws.
2. Khaws Tetramethylthiourea kom deb ntawm cov oxidizing muaj zog, vim kev sib cuag yuav ua rau muaj kev phom sij. Tiv thaiv los ntawm lub sij hawm raug rau huab cua thiab noo noo kom tswj cov khoom ruaj khov.
3. Ib txwm Tetramethylthiourea CAS 2782-91-4 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj thiab tsom iav kev nyab xeeb thaum tuav Tetramethylthiourea kom tsis txhob muaj plua plav tiv thaiv daim tawv nqaij, qhov muag, thiab khaub ncaws.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav, siv tag nrho cov khoom tiv thaiv tus kheej, thiab tsis txhob tsim cov plua plav. Muaj Tetramethylthiourea siv inert, tsis yog -cov khoom siv hluav taws xob nqus tau thiab tiv thaiv kev nkag mus rau hauv cov dej ntws lossis cov dej.
2. Ua tib zoo cheb los yog lub tshuab nqus tsev Tetramethylthiourea CAS 2782-91-4 siv cov txheej txheem tsim nyog thiab muab cov khoom khaws cia rau hauv ib lub thawv ntim tshuaj khib nyiab pov tseg kom raug pov tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog, suav nrog tus kheej - muaj lub tshuab ua pa yog tias tsim nyog, thaum ntxuav. Tetramethylthiourea raug suav hais tias tsis yog - muaj kev phom sij rau kev thauj mus los los ntawm qee qhov kev cai (NONH rau txhua hom kev thauj mus los).
Cov ntaub ntawv kev nyab xeeb
1. Tetramethylthiourea raug cais nrog GHS lub teeb liab lo lus "Ceeb toom" ua teeb meem yog nqos tau (H302). Nws kuj tseem tuaj yeem ua rau tawv nqaij thiab qhov muag khaus thaum sib cuag.
2. Tetramethylthiourea yog dawb mus rau yuav luag dawb crystalline khoom nrog lub melting point ntawm 75-80℃thiab ib tug boiling point ntawm 243-245 degree. Nws yog soluble hauv cov kuab tshuaj organic xws li acetone, chloroform, thiab toluene, tab sis insoluble hauv dej. Thermal decomposition yuav ua rau muaj kuab lom thiab irritating pa xws li carbon oxides, nitrogen oxides, thiab sulfur oxides.
3. Ib txwm Tetramethylthiourea CAS 2782-91-4 sab laj nrog Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Tetramethylthiourea kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P301+P312+P330 rau kev noj), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P264 (ntxuav daim tawv nqaij kom huv si tom qab tuav), P270 (tsis txhob noj, haus lossis haus luam yeeb thaum siv), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag). WGK Lub teb chaws Yelemees ntsuas yog 3 (siab txaus ntshai rau dej).
