The enthalpy of formation data appear in Table 1. Where there are numerous data for structurally related compounds, plotting the enthalpy of formation versus the number of carbons can reveal at a glance the quality of the data. For the alkyl hydroperoxides especially, the data are seen to be of mixed quality as evidenced by the lack of linearity in the plot (Figure 1). The error bars for the ethyl and n-propyl hydroperoxides are so large as to render the data meaningless. Also, the enthalpy of formation of n-propyl hydroperoxide is more negative than that of 1-hexyl hydroperoxide, another indication of its gross inaccuracy. The C2 and C3 hydroperoxide data will not be considered any further. 

For the comparison of hydroperoxides with methyl ethers (equation 2), we find there is enthalpy of formation data only for dimethyl ether, isopropyl methyl ether and t-butyl methyl ether (again ignoring the ethyl and propyl hydroperoxides). The enthalpies of formal reaction 2 for R = Me, i-Pr and f-Bu (two gas phase enthalpies of formation for f-BuOOH) are —53.1, —54.9 and —37.6 or —48.6 kJmoU, respectively, in the gas phase. In the liquid phase, the enthalpies of reaction are —7.4, —35 (from the estimated enthalpy of formation of isopropyl hydroperoxide) and —20.0 kJmoU, respectively. Because the enthalpy of formation deviations from linearity for dimethyl ether and methyl hydroperoxide might not be identical, the reaction enthalpy might not be consistent with those... 

As discussed in previous paragraphs, a disadvantage of TS-1 catalyst is its limited pore size, which restricts the number of oxidants that can be employed ° °. By using larger pore molecular sieves this restriction could be overcome. Titanium-substituted MCM-41 ° and titanium-grafted MCM-41 were shown to be particularly active in the epoxidation of bulky olefins like pinene and norbornene with TBHP. In the case of Ti-MCM-41 silicas, the importance of hydrophobicity in the system was demonstrated by the faster reaction rate observed with 2-methyl-l-phenyl-2-propyl hydroperoxide as the oxygen atom...
