    Abstract: An airbag inflator includes non-azide gas generating propellants, surrounding an ignition device, disposed inside a housing. The gas generating propellants are surrounded by a coolant/filter device having a pressure loss of 0.3x10 -2 to 1.5x10 -2 kg/cm 2 at a flow rate of 100 ℓ/min/cm 2 . A space is provided between an outer periphery of the coolant/filter device and the housing such that the combustion gas passes through the entire area of the coolant/filter device. The coolant/filter device is also surrounded by a swell suppressing layer which prevents the coolant/filter device from swelling due to a combustion of the gas generating propellants.

    Abstract: A catalyst component, e.g. copper chloride, is supported on (ii) an activated carbon obtainable from a vegetable or polymer raw material, (ii) a support having an aluminium content of 2% by weight or less, or (iii) a support having a sulfur content of 1% by weight or less to prepare a catalyst for synthesizing a carbonic diester. The catalyst has a high catalytic activity and reaction selectivity. The examples of said vegetable or polymer raw material include coconut shells or phenol resin respectively. The supporting amount of the catalyst component is about 0.5 to 80% by weight based on the support. A carbonic diester can efficiently be produced with a commercially high yield and selectivity by allowing an alcohol to react with carbon monoxide and oxygen in the presence of said catalyst.

    Abstract: An alcohol, e.g. methanol, carbon monoxide and oxygen are allowed to react in a gas phase in the presence of a solid catalyst comprising a catalyst component, for instance, containing halogen and copper atoms supported on a solid support. The alcohol and carbon monoxide contents of the reactor feed gas are controlled at 1 to 20 volume % and 70 to 95 volume %, respectively. Because the alcohol and carbon monoxide contents of the feed reactant gas are thus controlled, side reactions are considerably inhibited and the object carbonic diester is produced with high selectivity.
