Definition

Different sources of media describe the Definition of 40811-14-1 differently. You can refer to the following data:
1. A gaseous alkane obtained either from the gaseous fraction of crude oil or by the cracking of heavier fractions. The principal use of propane is as a fuel for heating and cooking, since it can be liquefied under pressure, stored in cylinders, and transported easily. Propane is the third member of the homologous series of alkanes.
2. propane: A colourless gaseous hydrocarbon,C3H8; m.p. –190°C; b.p.–42°C. It is the third member of thealkane series and is obtained from petroleum. Its main use is as bottledgas for fuel.

A Copper Metal–Organic Hydrogel as a Catalyst for SO2 and CO2 Fixation under Ambient Conditions

A copper metal–organic hydrogel (MOG) has been synthesized using an amino acid-based ligand, Na2HL {H3L = 2-{(3,5-di-tert-butyl-2-hydroxybenzyl)amino succinic acid} as a gelator. The metallohydrogel exhibits pH-responsive nature as well as chemical responsiveness. Besides, it shows rapid thixotropic behavior when external mechanical forces are applied. The metal–organic hydrogel can be used as a heterogeneous catalyst for the reaction of SO2 and CO2 with epoxides to produce cyclic 1,3,2-dioxathiolane-2-oxides and carbonates, respectively. The conversions were found to be dependent on the size and type of the side chain of the epoxides.

Synthesis of cyclic sulfites from epoxides and sulfur dioxide with silica-immobilized homogeneous catalysts

Quaternary ammonium- and amino-functionalized silica catalysts have been prepared for the selective synthesis of cyclic sulfites from epoxides and sulfur dioxide, demonstrating the effects of immobilizing the homogeneous catalysts on silica. The cycloaddition of sulfur dioxide to various epoxides was conducted under solvent-free conditions at 100 °C. The quaternary ammonium- and amino-functionalized silica catalysts produced cyclic sulfites in high yields (79-96 %) that are comparable to those produced by the homogeneous catalysts. The functionalized silica catalysts could be separated from the product solution by filtration, thereby avoiding the catalytic decomposition of the cyclic sulfite products upon distillation of the product solution. Heterogenization of a homogeneous catalyst by immobilization can, therefore, improve the efficiency of the purification of crude reaction products. Despite a decrease in catalytic activity after each recycling step, the heterogeneous pyridine-functionalized silica catalyst provided high yields after as many as five recycling processes. Immobilized for crimes of pyrolysis: Quaternary ammonium- and amino-functionalized silica catalysts promote the cycloaddition of sulfur dioxide to epoxides to produce cyclic sulfites in high yields (79-96 %) that are comparable to those with the homogeneous catalysts. Separation of the functionalized silica catalyst from the product solution by filtration avoids pyrolysis of the cyclic sulfites during purification by distillation. Copyright

Synthesis of hydroxy sulfonate surfactants

The selective synthesis of sulfonate surfactants with side chains containing ether- and hydroxy groups was carried out using cyclic sulfates as epoxide analogues. The main chain was elaborated from 1,2-dodecane sulfate by the addition of various hydroxy/alkoxysulfonates. Ethyleneoxy- and 1,2-propyleneoxy- groups were introduced using ethylene sulfate and 1,2-propylene sulfate, respectively.
