Triethyl Orthoformate (TEOF) (CAS: 122-51-0), Colorless ntshiab kua;irritating tsw.Cov nplaim taws heev.me ntsis soluble hauv dej;soluble hauv cawv, ether;decomposes hauv dej.
Alkylating Reagents rau Ester Synthesis;Novel Powerful N-Formylating Reagent;Formylation Reagents.
Triethyl Orthoformate yog ib qho tseem ceeb organic synthesis reagent rau acetylization, imidic ester tsim, thiab activated aromatic hom formation.A reagent pab tau rau acetylization thiab imidic ester tsim.
Triethyl Orthoformate yog siv nyob rau hauv Bodroux-Chichibabin aldehyde synthesis los npaj ib qho aldehyde nrog ib tug carbon siab dua los ntawm reacting nrog Grignard reagent.Nws kuj yog siv nyob rau hauv lub electrophilic formylation ntawm activated aromatic hom xws li phenol.
Siv los ua cov khoom siv tshuaj, nws yog cov khoom siv hluavtaws ntawm cov tshuaj tiv thaiv kab mob xws li chloroquine thiab quinquine.Nws kuj yog siv nyob rau hauv kev npaj ntawm high polymers, cov tshuaj yees duab, cov ntaub ntawv photosensitive, anti-Halo dyes, cyanine dyes thiab tshuaj tua kab hluavtaws.Siv los ua lwm yam tshuaj.
Triethyl Orthoformate muaj ntau yam kev siv, suav nrog ua cov tshuaj reagent hauv cov organic synthesis, rau kev npaj cov chiral compounds, thiab ua ib qho catalyst rau kev tsim cov polymers.Nws kuj tseem siv los ua cov yas yas, ua cov kuab tshuaj rau cov resins thiab cellulose acetate, thiab ua cov roj ntxiv.
Triethyl Orthoformate raug suav hais tias yog tshuaj lom neeg, thiab yuav tsum tau ua raws li kev tiv thaiv kev nyab xeeb tsim nyog.Triethyl Orthoformate yog cov nplaim hluav taws kub heev thiab yuav tsum tau muab cia kom deb ntawm tshav kub thiab qhib nplaim taws.Kev sib cuag nrog daim tawv nqaij thiab qhov muag yuav tsum zam.Kev nqus pa ntawm vapors tuaj yeem ua rau khaus rau ntawm lub ntsws thiab yuav tsum zam.
Muaj tshuaj lom los ntawm kev noj tshuaj.Mddly lom los ntawm kev nqus pa, sib cuag ntawm daim tawv nqaij, thiab txoj hauv kev subcutaneous.Ib daim tawv nqaij thiab qhov muag irritant.Qhov phom sij txaus ntshai heev thaum raug tshav kub lossis nplaim taws;tuaj yeem cuam tshuam nrog cov khoom siv oxidizing.Txhawm rau tua hluav taws, siv ua npuas ncauj, CO2, tshuaj qhuav.Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes.Saib ESTERS thiab.
Triethyl Orthoformate yog ester.Esters teb nrog cov kua qaub kom tso cua sov nrog rau cov cawv thiab cov kua qaub.Muaj zog oxidizing acids tuaj yeem ua rau cov tshuaj tiv thaiv muaj zog uas txaus exothermic rau ignite cov tshuaj tiv thaiv cov khoom.Thaum tshav kub kub kuj yog tsim los ntawm kev sib cuam tshuam ntawm esters nrog cov tshuaj caustic.Flammable hydrogen yog tsim los ntawm kev sib xyaw esters nrog alkali hlau thiab hydrides.
Tej zaum yuav ua rau muaj tshuaj lom yog tias nqus tau los ntawm daim tawv nqaij.Kev nqus tau los yog sib cuag nrog cov khoom yuav ua rau khaus lossis hlawv tawv nqaij thiab qhov muag.Hluav taws yuav ua rau khaus, corrosive thiab/los yog cov pa phem.Vapors tuaj yeem ua rau kiv taub hau lossis ua tsis taus pa.Cov dej ntws los ntawm kev tswj hluav taws kub lossis dej dilution tuaj yeem ua rau muaj kuab paug.
HIGHLY FLAMMABLE: Yuav tau yooj yim ignited los ntawm tshav kub, sparks los yog nplaim taws.Vapors tuaj yeem tsim cov khoom tawg nrog cua.Vapors tuaj yeem mus rau qhov chaw ntawm qhov hluav taws kub thiab rov qab flash.Feem ntau cov vapors hnyav dua li huab cua.Lawv yuav kis tau mus rau hauv av thiab sau rau hauv qhov chaw qis lossis qhov chaw kaw (sewers, hauv qab daus, tso tsheb hlau luam).Vapor explosion txaus ntshai nyob hauv tsev, sab nraum zoov lossis hauv cov kav dej.Cov dej ntws mus rau hauv cov kav dej yuav ua rau muaj hluav taws kub lossis tawg.Cov thawv ntim khoom tuaj yeem tawg thaum cua sov.Cov kua dej ntau yog sib dua li dej.
Flammable, nruab nrab hluav taws kub txaus ntshai.
Nyob rau hauv cov ntaub ntawv ntawm cov nplaim taws, kub kub, flammable oxidant;combustion stimulus pa luam yeeb.
