But these wildfire toxins, which include benzene, styrene, formaldehyde and cadmium, aren't the kind of chemical that can be easily purged with a $16 "Royal Defense" smoothie from upscale grocery ...
2 is about 10 −3, [1] while that of formaldehyde H 2 C =O to methanediol H 2 C(OH) 2 is 10 3. [2] For conversion of hexafluoroacetone (F 3 C) 2 C =O to the diol (F 3 C) 2 C(OH) 2, the constant is about 10 +6, due to the electron withdrawing effect of the trifluoromethyl groups. Similarly, the conversion of chloral (Cl
