Ronson Consumer Products Corporation was formerly based in Somerset, New Jersey.It is a producer of lighters and lighter accessories.. Zippo Manufacturing Company currently owns the related brands in the United States, Canada, and Mexico, and continues to produce Ronson lighters and Ronsonol fuel.
English: Newman projections of butane conformations & their relative energy differences (not total energies). Conformations form when butane rotates about one of its single covalent bond. Torsional/dihedral angle is shown on x-axis. Conformations (according to IUPAC): A: antiperiplanar, anti or trans B: synclinal or gauche C: anticlinal or eclipsed
n-Butane: Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. Vapor pressure of n -butane . From formula: log 10 P m m H g = 6.83029 − 945.90 240.0 + T {\displaystyle \scriptstyle \log _{10}P_{mmHg}=6.83029-{\frac {945.90}{240.0+T}}} obtained from Lange's Handbook of Chemistry , 10th ed.
Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application.
Such diagrams are available in the speciality literature. [1] [2] [3] The same information can be depicted in a normal orthogonal diagram, showing only two substances, implicitly using the feature that the sum of all three components is 100 percent. The diagrams below only concerns one fuel; the diagrams can be generalized to mixtures of fuels.
For example, butane has three conformers relating to its two methyl (CH 3) groups: two gauche conformers, which have the methyls ±60° apart and are enantiomeric, and an anti conformer, where the four carbon centres are coplanar and the substituents are 180° apart (refer to free energy diagram of butane).
Steam cracker units are facilities in which a feedstock such as naphtha, liquefied petroleum gas (LPG), ethane, propane or butane is thermally cracked through the use of steam in steam cracking furnaces to produce lighter hydrocarbons. The propane dehydrogenation process may be accomplished through different commercial technologies.
A butane torch is a tool which creates an intensely hot flame using a fuel mixture of LPGs typically including some percentage of butane, a flammable gas. Consumer air butane torches are often claimed to develop flame temperatures up to approximately 1,430 °C (2,610 °F).
