text: "The decarbonization of the energy supply is one of the biggest and most important
challenges of the 21st century. This paper contributes to the solution of the
energy crisis by investigating the stability of alcohols as e-fuels. The focus
is on the investigation of the aging mechanism of the linear alcohols 1-hexanol
and 1-octanol compared to the iso-alcohol 2-hexanol. It is analysed in detail
how the time-dependent aging varies depending on the chain length and the position
of the hydroxy-group, both in the liquid and in the gas phase. It is shown that
a variety of aging products such as aldehydes, acids, short-chain alcohols and
esters are formed during the aging of the n-alcohols by oxidation, decarboxylation,
oxidative C-C bond cleavage and esterification. In contrast, the decomposition
of the iso-alcohol is significantly lower. The results show that the total acid
number is significantly higher for aged n-alcohols than for the aged iso-alcohos,
while the kinematic viscosity decreases for all alcohols during aging. Carbon
mass balancing shows that after accelerated aging for 120 hours, around 80% of
the iso-alcohol is still present, compared to only around 57-63% for the n-alcohols.
In addition, significantly fewer acids are formed with the iso-alcohol. In this
study, iso-alcohols have a higher stability against thermo-oxidative aging compared
to n-alcohols, showing their potential as e-fuels. Furthermore, the chain length
of the alcohols has also an influence on aging, as more different aging products
can be formed with increasing chain length.\r\n\r\nThis paper contributes to the
solution of the energy crisis by investigating the stability of alcohols as e-fuels.
The focus is on the investigation of the aging mechanism of 1-hexanol and 1-octanol
compared to the 2-hexanol."
