| Volatile raw material supply, including n-butane and benzene, is expected to remain a key challenge for industry participants over the next five years. |
| Benzene and N-butane are covered under the upstream raw materials prices analysis section of this research on maleic anhydride market. |
| First, the spectra are heavily overlapping as seen in Figure 2 where the mid-infrared absorption spectra of methane, ethane, propane and n-butane are shown. |
| A fatal case of n-butane poisoning after inhaling anti-perspiration aerosol deodorant. |
| Thus a longer process of synthesis of natural gas hydrates leads to the consistent increase of the ethane concentration, n-butane, propane and i-butane in the clathrate phase. |
