It is concluded that Fatty acids, C14-22, 2-ethylhexyl esters, epoxidized acid is unlikely to undergo rapid decomposition with the evolution of gases or release of heat and does not present a risk of explosion.
Reference
CcHhOo + [c + (h/4) – (o/2)] O2 c CO2 + (h/2) H2O
Using the formula:
Oxygen balance = -1600 x [(2.c) +(h/2)-O]/molecular weight
If there is a deficiency of oxygen present, the balance is negative, while an excess of oxygen gives a positive balance, and such compounds can act as oxidants and may be explosive in nature. The balance is expressed as a percentage. Nitrogen is not considered oxidizable and is usually liberated as the gaseous element during explosive decomposition. Materials or systems approaching stoichiometric composition (zero oxygen balance) are the most powerfully explosive, giving maximum heat energy release. There are known explosives with an oxygen balance of -64%. Compounds with an oxygen balance more negative than -200% are not considered to pose an explosive risk.
The oxygen balancethe 3 main components of ED6 (C18 oxirane 2-ethylhexyl ester, C18 dioxirane 2-ethylhexyl ester, C18 trioxirane 2-ethylhexyl ester) comprising ~ 80% of ED6are calculated as follows:
C12 oxirane 2-ethylhexyl ester
The molecular formula isC20H38O3
MW=326.52
Oxygen balance = -1600 x [(2 x 20) + (38/2) – 3] /326.52
Oxygen balance = -274.41 %
The oxygen balance of C12 oxirane 2-ethylhexyl esteris substantially more negative than -200%.
C18 oxirane 2-ethylhexyl ester
The molecular formula isC26H50O3
MW=410.69
Oxygen balance = -1600 x [(2 x 26) + (50/2) – 3] /410.69
Oxygen balance = -288.3 %
The oxygen balance of C12 oxirane 2-ethylhexyl esteris substantially more negative than -200%.
C18 dioxirane 2-ethylhexyl ester
The molecular formula isC26H48O4
MW=424.67
Oxygen balance = -1600 x [(2 x 26) + (48/2) – 4] /424.67
Oxygen balance = -271.27 %
The oxygen balance ofC18 dioxirane 2-ethylhexyl esteris substantially more negative than -200% .
