When the chain length of alkoxy group of the adipates increases, diethyl adipate, dimethyl adipate and dipropyl adipate can depress the saturation vapor pressure lower than that of gasoline, among which dipropyl adipate is the most effective one.
The results show that the length of alkoxy group effects on the phase stability of methanol-gasoline significantly.
As the carbon atoms of the alkoxy group increase over 4 the esters can stabilize the methanol-gasoline at low temperature.
As a rule, larger alkyl groups on a silane will have lower VOC, and a higher alkoxy group will have lower VOC.
In addition, capture of the excess moisture coming from the surrounding environment by the hydrolysis reactions of active alkoxy groups in silane can also be expected, by which the free-state water absorption can be consumed (27).
However, once the silanes have been hydrolyzed or reacted to the mineral surface, the nature of the alkoxy group is no longer an issue.
One end of the alkoxy group reacts with the silanol group on the silica surface via a hydrolysis mechanism (refs.
In this reaction, the end group of the ethylenic polymer will be the alkoxy group from the peroxide (figure 7).
Although the methoxy group is considered to be superior to diminish merely the silanol groups of the silica during the mixing in the silica-filled compounds, these results indicate that the ethoxy group is the best alkoxy group to improve the processing characteristics.
In the presence of moisture, hydrolizable alkoxy group leads to the formation of silanols.
The substitution of the alkoxy group not only enhances the delocalization [pi]-electrons in the copolymer, but also acts as a solubilizing group.
This step of reaction is basically a transesterification process where the exchange of the alkoxy group of an ester compound by another alcohol takes place.
