The formal isomerization enthalpies of methyl n-butyl ether to methyl terf-butyl ether and of di-n-butyl ether to n-butyl ferf-butyl ether are about —24kJmoU (Iq) and —26.5 kJmol (g), respectively. From these, and the experimental enthalpy of formation of di-ferf-butyl peroxide, the enthalpies of formation of di-n-butyl peroxide are ca —333 kJmol (Iq) and —288 kJmol (g), wildly divergent from the reported values.

The atmospheric destruction of methyl n-butyl ether will occur primarily via reaction with OH, with NO3 and Cl-atoms potentially playing a role. The lifetime against OH attack is estimated to be about 8 h, for a daytime [OH] 2.5 x 10 molecule cm . ... 

The OH-initiated oxidation of methyl n-butyl ether has been studied in detail by Aschmann and Atkinson (1999a). Observed products, with molar yields in parentheses, were as follows methyl formate (51 11%), propanal (43 6%), butanal (4.5 1%), methyl butyrate ( 1.6%), and CH3C(0)CH2CH20CH3 and/or CH3CH2C(0)CH20CH3 (19 4%). Products with molecular weights of 118, 149, and 165, corresponding to five-carbon hydroxycarbonyls, nitrates, and hydroxynitrates, were also identified.
