Although acetaldehyde, acrolein, and propionaldehyde
have less than optimal recovery rates with the 98.
The factory had produced the flavoring agents using banned substances, including acetaldehyde, propionaldehyde
and castor oil, since 1992 when it received a license to produce them and other products, according to Ibaraki prefectural health authorities.
High-performance liquid chromatographic method for the simultaneous detection of malonaldehyde, acetaldehyde, formaldehyde, acetone and propionaldehyde
to monitor the oxidative stress in heart.
Simultaneously, Union Carbide will expand capacity by 40% for production of methylmercapto propionaldehyde
(MMP), the major derivative of acrolein.
These are methanol, phenol, formaldehyde, acetaldehyde, propionaldehyde
, and acrolein.
The five substances are acetaldehyde, propionaldehyde
, castor oil, dimethylbutylaldehyde and isopropanol.
NCASI Method 105 was used during lumber drying to measure emissions of methanol, phenol, formaldehyde, acetaldehyde, propionaldehyde
, and acrolein from red alder (Alnus rubra), ponderosa pine (Pinusponderosa), white wood (a mix of western pines, fir, and spruce), Douglas-fir (Pseudotsuga menzeisii), western hemlock (Tsuga heterophylla) and white spruce (Picea glauca).
The ingredients -- acetaldehyde, propionaldehyde
and castor oil -- were used by Tokyo-based flavor maker Kyowa to flavor products made at its factory in Ibaraki Prefecture.
