A sublimatory [1] [2] or sublimation apparatus is equipment, commonly laboratory glassware, for purification of compounds by selective sublimation. In principle, the operation resembles purification by distillation , except that the products do not pass through a liquid phase .
Cold finger used in sublimation.The raw product (6) is in the bottom of the outer tube (4) which is heated (7) while under vacuum (through side-arm 3). The sublimated material collects (5) on the cold finger proper, cooled by a coolant (blue) circulated through ports 1 and 2.
Sublimate also refers to the product obtained by sublimation. [2] [3] The point at which sublimation occurs rapidly (for further details, see below) is called critical sublimation point, or simply sublimation point. Notable examples include sublimation of dry ice at room temperature and atmospheric pressure, and that of solid iodine with heating.
Vicks VapoRub is made of ingredients such as camphor, eucalyptus oil and menthol. When placed on the skin, camphor can be absorbed through mucous membranes or broken skin. This also can be toxic ...
Both naphthalene and 1,4-dichlorobenzene undergo sublimation, meaning that they transition from a solid state directly into a gas; this gas is toxic to moths and moth larvae. [ 1 ] Due to the health risks of 1,4-dichlorobenzene, and flammability of naphthalene, other substances like camphor are sometimes used.
CO 2 snow cleaning was further developed by the Fraunhofer Institute for Manufacturing Engineering and Automation IPA, for the purpose of removing paint from aircraft fuselages. [9] Nozzle design is the most significant factor in carbon dioxide snow cleaning performance, affecting the size and velocity of the dry ice particles.
