The use of tetrahydrobenzoxazines I
where R
1
is a hydrocarbyl radical and R
2
, R
3
, R
4
and R
5
are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals, and where R
2
to R
5
may also form a second and a third tetrahydrooxazine ring, with the proviso that at least one of the substituents has from 4 to 3000 carbon atoms and the remaining substituents, when they are hydrocarbyl radicals, each have from 1 to 20 carbon atoms, as stabilizers for stabilizing inanimate organic material, especially turbine fuels, against the action of light, oxygen and heat.
使用四氢苯并
噁唑,其中R1为烃基基团,R2、R3、R4和R5分别独立地为氢原子、羟基或烃基基团,其中R2到R5还可以形成第二个和第三个四氢
噁唑环,但至少有一个取代基含有4到3000个碳原子,其余的取代基(当它们是烃基基团时)每个都含有1到20个碳原子,作为稳定剂,以稳定无机有机材料,特别是涡轮燃料,防止光、氧和热的作用。
