Carbon tetrachloride, tseem paub los ntawm ntau lwm lub npe yog cov organic compound nrog cov tshuaj formula CCl₄. Nws yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw "qab zib" uas tuaj yeem kuaj pom ntawm qib qis. Nws yog xyaum tsis flammable ntawm qhov kub thiab txias.
Vim li cas Tetrachloromethane tsis yaj hauv dej?
Raws li CCl4 yog cov tsis muaj polar compounds yog li lawv yaj hauv cov kuab tshuaj tsis muaj polar tab sis raws li dej yog cov kuab tshuaj polar yog li nws tsis yaj hauv cov kuab tshuaj zoo li no.
Puas yog Tetrachloromethane miscible nrog dej?
Cov kua tsis muaj xim tsis muaj xim nrog cov ntxhiab tsw, zoo li insoluble hauv dej tab sis miscible nrog ntau cov kua organic, xws li ethanol thiab benzene; r.d. 1.586; m.p. -23 ° C; b.p ib. 76.54°C dej. Nws yog tsim los ntawm chlorination ntawm methane (yav dhau los los ntawm chlorination ntawm carbon disulphide).
Yuav carbon tetrachloride puas yaj hauv dej?
Ethyl cawv yuav luag yog cov dej molecule, H3C-CH2OH, thiab yog li H3COH; ob qho tib si molecules muaj peev xwm ntawm kev sib cuam tshuam nrog dej los ntawm hydrogen bonding, thiab ob qho tib si molecules yog infinitely miscible nyob rau hauv dej. … Ntawm qhov tod tes, carbon tetrachloride yog ib qho tsis muaj polar molecule, thiab yuav pom cov dej tsis zoo heev.
YPuas toluene soluble hauv dej?
Nws muaj qab zib, pungent benzene zoo li tsw. Toluene muaj qhov hnyav molecular ntawm 92.14 g mol−1. Ntawm 25 ° C, toluene muaj solubility hauv dejntawm 526 mg l−1 , kwv yees vapor siab ntawm 28.4 mm Hg thiab Henry's Law Constant ntawm 6.64 × 10 −3 atm-m3 mol− 1(USEPA, 2011).
