Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water and other trace elements. Dry cleaning is any cleaning process for clothing and textiles using a solvent other than water.. Dry cleaning still involves liquid, but clothes are instead soaked in a water-free liquid solvent, tetrachloroethylene (perchloroethylene), known in the industry as "perc", which is the most widely used solvent. Dry ice is the name for solid carbon dioxide. Carbon dioxide (chemical formula CO 2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. polytetrafluoroethylene (PTFE). Solution containing not more than 20% of these compounds in non-reactive solvents, however, can be handled without risk of spontaneous ignition. Silicon dioxide, also known as silica and quartz, is very abundant in the universe and has a large temperature range where it is liquid. Acetonitrile, often abbreviated MeCN (methyl cyanide), is the chemical compound with the formula CH 3 CN and structure H 3 CCN.This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic).It is produced mainly as a byproduct of acrylonitrile manufacture.
