Urbanski and Sion (Ref 3) later prepd it in small quantities, together with 1-nitropropane, on treating n-propane vapor with gaseous nitrogen. More recently, Kisp ersky et al (Ref 5) prepd a product from 1,3-diiodopropane and Ag nitrate which was stable for at least 9 months Its Na compd, C3Hs(N02)2Na, was prepd by Keppler Meyer (Ref 2), and was reported to be a violent expl ( heftig explodierendes pulver in Ger)...

In the hydroxylation of n-propane to n-propanol by Nocardia paraffinicum (Rhodococcus rhodochrous) ATCC 21198, the ratio of hydrocarbon to oxygen consumed was 2 1 and this suggests that the reaction of two molecules of propane and one molecule of dioxygen... 

Only the thermal design will be done. The physical properties of the mixture will be taken as the mean of those for n-propane (MW = 44) and n-butane (MW = 58), at the average temperature.

To a solution of 2,6-diamino- 4,5,6,7-tetrahydro-benzthiazole in dimethylformamide are added n-propanal and the mixture is heated to 50°C for 1 hour. After cooling, the reaction solution is mixed with sodium borohydride and heated to 50°C for 30 min. The solvent is largely eliminated in vacuo. Whilst cooling with ice, the residue is mixed with water and 2 N hydrochloric acid until a pH of 1 is obtained. The aqueous solution is extracted...

Methyl glyoxal has never been reported in soy sauce or soy bean paste prior to this study. Certain aldehydes (acetaldehyde, n-propanal, 2-methylpropanal, and 3-methylbutanal) were found in soy sauce previously (32). A gas chromatogram of the extract from cysteamine-treated soy sauce and untreated soy sauce are shown in Figures 7 and 8. 

The most common members of aliphatic hydrocarbons are methane, ethane, n-propane, n-butane, n-pentane, n-hexane, n-heptane, n-octane, n-nonane, and n-decane. In general, after repeated exposure, these compounds cause nausea, vomiting, abdominal discomfort, asphyxia, and chemical pneumonitis. In high concentrations as gas or vapor, these compounds trigger CNS depression and axonopathy. Keeping up the essential requirements of chemical safety to industrial workers, the ACGIH and OSHA have set the threshold limits for many of the aliphatic hydrocarbons. ...
