Cov kua tsis muaj xim nrog cov ntxhiab tsw zoo. Yooj yim heev. Flash point 70 degree F. Tsawg ntom dua dej. Vapors hnyav dua li huab cua. Siv los ua cov kuab tshuaj thiab ua cov tshuaj pleev ib ce. |
| Cua & Dej Reactions |
Cov nplaim taws heev. Soluble hauv dej. Tej zaum yuav maj mam tsim cov khoom peroxidized thaum raug huab cua. Cov tsim peroxide zoo li yuav tsis ruaj khov. |
| Reactivity Profile |
Ethers, xws li DIETHOXYPROPENE, tuaj yeem ua lub hauv paus. Lawv tsim cov ntsev uas muaj zog acids thiab ntxiv complexes nrog Lewis acids. Lub complex ntawm diethyl ether thiab boron trifluoride yog ib qho piv txwv. Ethers tuaj yeem hnov mob hnyav nrog cov tshuaj oxidizing muaj zog. Hauv lwm cov tshuaj tiv thaiv, uas feem ntau cuam tshuam nrog kev rhuav tshem cov pa roj carbon-oxygen daim ntawv cog lus, ethers kuj tsis muaj zog. |
| Health Hazard |
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 tuaj yeem ua rau muaj kuab paug. |
| Hluav Taws Xob |
HIGHLY FLAMMABLE: Yuav tau yooj yim ignited los ntawm tshav kub, sparks los yog nplaim taws. Cov 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, tanks). 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. |
| Kev ruaj ntseg Profile |
Cov ntaub ntawv hloov pauv tau tshaj tawm. Ib tug flammable kua. Qhov phom sij txaus ntshai thaum raug tshav kub, nplaim taws, lossis oxiduers. Thaum rhuab mus rau decomposition nws emits pa taws thiab pa taws. |
| Ntxim yuav nphav raug |
Siv los ntawm cov neeg muaj peev xwm tsim nyog nkaus xwb; nyob rau hauv cov organic synthesis. US EPA raws li TSCArestricts siv cov tshuaj no rau R&D nkaus xwb. |
| Kev pab thawj zaug |
Yog hais tias cov tshuaj no nkag mus rau hauv lub qhov muag, tshem tawm ib qho kev sib cuag lo ntsiab muag ib zaug thiab irrigate tam sim ntawd rau tsawg kawg yog 15 feeb, qee zaus nqa lub hau sab sauv thiab qis dua. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no kis rau ntawm daim tawv nqaij, tshem tawm cov khaub ncaws tsis huv thiab ntxuav tam sim nrog xab npum thiab dej. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no tau nqus tau lawm, tshem tawm ntawm qhov raug, pib ua pa cawm siav (siv kev ceev faj thoob ntiaj teb, suav nrog daim npog qhov ncauj resuscitation) yog ua tsis taus pa thiab CPR yog tias lub plawv nres. Hloov tam sim ntawd mus rau qhov chaw kho mob. Thaum cov tshuaj no tau nqos lawm, mus ntsib kws kho mob. Muab dej ntau thiab ua kom ntuav. Tsis txhob ua rau tus neeg tsis nco qab ntuav. |
| khaws cia |
Xim Code-Red: Flammability Hazard: Khaws rau hauv qhov chaw cia cov kua hluav taws xob lossis lub txee tso cai kom deb ntawm qhov chaw taws teeb thiab cov khoom siv corrosive thiab reactive. Ua ntej ua haujlwm nrog cov tshuaj no koj yuav tsum tau kawm txog nws txoj kev tuav thiab khaws cia. Khaws rau hauv cov thawv kaw kom nruj rau hauv qhov chaw txias, qhov cua zoo kom deb ntawm cov kua qaub thiab muaj zog oxidizers. Qhov chaw ntawm qhov hluav taws kub, xws li kev haus luam yeeb thiab cov nplaim taws, raug txwv qhov twg diethoxypropene raug tuav, siv, lossis khaws cia. Cov thawv hlau uas cuam tshuam txog kev hloov ntawm 5gallons lossis ntau dua ntawm diethoxypropene yuav tsum tau muab tso rau hauv av thiab sib txuas. Nruas yuav tsum tau nruab nrog tus kheej-kaw li qub, lub tshuab nqus tsev bungs, thiab nplaim taws ntes. Siv cov cuab yeej thiab cov khoom siv tsis muaj pa taws, tshwj xeeb tshaj yog thaum qhib thiab kaw cov thawv ntawm diethoxypropene. Txhua qhov chaw siv diethoxypropene, tuav, tsim, lossis khaws cia, siv cov khoom siv hluav taws xob tawg thiab cov khoom siv hluav taws xob. |
| Kev xa khoom |
3, 3-Diethoxypropene yuav tsum dais "FLAMMABLE LIQUID" daim ntawv lo. Nws ntog hauv Hazard Class 3 thiab Packing Group II. |
| Txoj Kev Purification |
Ntxiv Na2CO3 (ca 3.5%) thiab distil nws siv ib kem npaum, los yog zoo dua siv ib tug spinning band kem. [Witzemann et al. Org Synth Coll Vol II 17 1943, Beilstein 1 H 727, 1 I 378, 1 III 2960, 1 IV 3437.] |
| Kev tsis sib haum xeeb |
Cov ntaub ntawv tawg sib xyaw nrog huab cua.Kev sib cuag nrog cov kua qaub thiab cov oxidizers muaj zog yuav ua rau muaj hluav taws kub thiab tawg. |
