Under flash vacuum pyrolysis, dioxabicyclo[n.2.1]alkanes (n= 3,4, and 5) isomerise to keto-aldehydes, MeCO[CH2]nCHO, whereas dioxabicyclo[n.2.2]alkanes (n= 2,3, and 4) fragment ot give, by loss of hydrogen and ethylene, mixtures of cycloalkane-1,4-diones and dialdehydes, OHC[CH2]nCHO.
在快速真空热解下,二氧杂双环[ n .2.1]烷烃(n = 3,4和5)异构化为酮醛MeCO [CH 2 ] n CHO,而二氧杂双环[ n .2.2]烷烃(n = 2,3和4)片段ot通过氢和乙烯的损失得到环烷-1,4-二酮和二醛的混合物,OHC [CH 2 ] n CHO。

(b) an aromatic tricarboxylic acid anhydride, and
(c) an aromatic diisocyanate,
can be used as coating composition for metal surfaces.
