Waxes and Greases

The lower molecular weight oils, waxes, and greases of PCTFE can be prepared direcdy by telomerization of the monomer or by pyrolysis of the higher molecular weight polymer (45—54).

The lower molecular weight PCTFE oils, waxes, and greases are used as inert sealants and lubricants for equipment handling oxygen and other oxidative or corrosive media. Other uses include gyroscope flotation fluids and plasticizers for thermoplastics. 

Dry Cleaning. Condensed phase carbon dioxide is also used as a solvent for the dry cleaning of clothes. Although carbon dioxide alone is not a good solvent for oils, waxes, and greases, the use of carbon dioxide in combination with a surfactant allows for the replacement of perchloroethylene (which is the solvent used most often to dry clean clothes, although it poses hazards to the environment and is a suspected human carcinogen). 

Waxes and greases are employed as temporary protectives. Steel sheets, bars, tubes, etc. are transported with a water-repellent film of oil or grease. A secondary method of protecting car bodies, especially door and sill voids, is to spray wax through the small access ports and form an even layer which protects the metal from water, salt, and road dirt.

Carbon disulfide is an important solvent for waxes and greases. Methane is the principal component of natural gas. Nitrogen dioxide is used for making nitric acid and is also an atmospheric pollutant. All three compounds contain covalent bonds in which the sharing of electrons is more or less equal. 

The name "Apiezon" is a trade name for all types of vacuum waxes and greases. One of these waxes is known as black wax. It is applied by heating it with a burner and then applying it to the glass where the leak is. Find out something about what black wax is made of and what it will dissolve in so it can be removed. 

Products and Uses An emulsifier (aids in suspension of oily liquids), lubricant, and plasticizer in cosmetics, skin creams, facial makeups, plastics, waxes, and greases, varnishes, lacquers, and lubricants. 

SOLVENOL 226 terpene solvent is a pale yellow to near colorless liquid that has high solvency for resins, waxes, and greases. Of pinewood origin, it is a mixture of monocyclic terpenes rich in para -rnemhane. It is used as a solvent in the manuficture of deanmg compounds textile dyes waxes and polishes for floor, fiunimre, leather, and shoes and in other chemical specialties. 

The lachrymators 2-chloroacetophenone and o-chlorobenzylmalonitrile in tear gas, bank security devices, etc., have been identified by GC-MS. Capillary GC has been utilized to discriminate waxes and greases in cosmetic materials such as lipsticks submitted in forensic casework. For applications of this sort the recent improvements in high-temperature GC are very useful.

The solvents that are mostly employed include volatile organic solvents (VOCs) like methylene chloride, chloroform, perchloroethylene (PERC) and carbon tetrachloride. Some VOCs like, isopropyl alcohols, xylenes, toluenes and ethylenes have been used as cleaning fluids because of their ability to dissolve oils, waxes and greases. Also, they readily evaporate from the items that they are being used to clean (VOCs readily evaporate or vaporise at room temperature). When VOCs come in contact with sun light and nitrogen oxides (by-products from the combustion of fossil fuels), these are transformed into ozone, nitric acid and partially oxidised organic compounds. 

Bottom of the barrel fractions - atmospheric and vacuum residues - can be converted by the processes described in Sections 2 and 3, or they can be used to make lubes, waxes and greases. 

Uses Solvent scour for removing oils, wax and grease tfom goods prior to dyeing Properties Liq. 100% cone.
