| Methane is a colourless odourless gas, CH4; m.p. is -182.5°C; b.p. is -164°C. Methane is the simplest hydrocarbon. It is the first member of the alkane series. It is the main constituent of natural gas (-99%) and is an important raw material for producing other organic compounds. Chemists can convert it into methanol by catalytic oxidation.

Modern laboratories of organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, colloidal chemistry, and electrochemistry have running water and gas. Every chemical laboratory has a ventilating hood for the escape of harmful odours and vapors. Every laboratory has lightening and different types of equipment. All chemical laboratories have benches. These benches have a lot of drawers. Chemists keep their materials and devices in these drawers. Chemical laboratories also have many shelves and cases. Chemists keep their containers with chemicals in these cases. Flasks, weighing bottles, test-tubes, beakers, funnels, evaporating dishes are on the benches. Chemists keep their glassware in good order. Some chemical laboratories, for example of the laboratories of physical chemistry have a microscope. Chemists use this device when they need to describe the properties of a substance or define what substances they obtained after experiment. There are many burners in the chemical laboratory, for example Bunsen burner. Chemists use burners when they need to produce flame. Chemists use crucibles. They use crucibles when they need to heat a solution, ignite materials. People make crucibles of quartz, porcelain and iron. Also I know platinum crucibles. Chemists use platinum crucibles very seldom.
