Frozen hydrocarbons
WebThis causes the ice to melt and the methane to escape. Several other names are commonly used for methane hydrate. These include: methane clathrate, hydromethane, methane … WebAs has been observed before, frozen ammonia solution looked glassy, with regular polygonal cracks at a spac-ing of roughly 1cm. All the hydrocarbons and nitriles studied formed white solids, sometimes waxy in ap-pearance. Methanol was more transparent, with ~2-3mm wide needle-like crystals.
