Umahluko phakathi kweNqanaba le-AT kunye ne-CT

Iiklasi A no-C zibonisa iindawo apho izinto eziyingozi zigcinwa khona, ngomlinganiselo ophezulu wobungqina bokudubula kweCT.

Iqela legesi/iqela lobushushu	T1	T2	T3	T4	T5	T6
IIA	I-formaldehyde, itoluene, imethyl ester, iacetylene, propane, iacetone, iasidi ye-acrylic, benzene, isitayile, icarbon monoxide, i-ethyl acetate, iacetic acid, iklorobenzene, i-methyl acetate, iklorine	IMethanol, i-ethanol, ethylbenzene, ipropanol, ipropylene, ibutanol, butyl acetate, i-amyl acetate, i-cyclopentane	IPentane, ipentanol, hexane, i-ethanol, iheptane, iokteni, cyclohexanol, iturpentine, naphtha, i-petroleum (kuquka nepetroli), amafutha amafutha, pentanol tetrachloride	IAcetaldehyde, trimethylamine		I-Ethyl nitrite
IIB	Ipropylene ester, idimethyl ether	Butadiene, epoxy propane, ethylene	Idimethyl ether, acrolein, i-hydrogen carbide

ETshayina, Udidi A lubandakanya iindawo ezinepropane, ngelixa udidi C lubandakanya iindawo ezinerhasi ezinjengehydrogen kunye neacetylene.
