Semicarbazine/manganese complex and gas generator for air bag

Air bag gas generating composition

Cyclohexadiene derivatives represented by the formula (I) ##STR1## (wherein --X-- represents ##STR2## --Y-- represents ##STR3## and R.sup.1 and R.sup.2 represent a lower alkyl group) and a process for preparing the same.

Cyclohexadiene derivatives and process for preparing the same

A pyran derivative represented by the formula ##STR1## wherein R.sub.1 and R.sub.4 are each the same or different alkyl having 1 to 6 carbon atoms, R.sub.2 and R.sub.3, when attached to a nitrogen atom, forms a saturated hetrocyclic ring which has as a hetero atom a nitrogen atom is addition to the nitrogen atom attached to R.sub.2 and R.sub.3, or oxygen atom, and an acid addition salt thereof. The compounds have antibacterial and insecticidal action.

Heterocyclic containing 5-oxo pyrans

2,2'-BIS(3,4-Epoxy-5-oxotetrahydropyran)ethers represented by the formula ##STR1## wherein R is hydrogen atom or straight-chain or branched-chain alkyl having 1 to 6 carbon atoms; a process for preparing the same.
