Non-flammable

Trichloroethane [71-55-6] methyl chloroform, CH CCl, is a colorless, non-flammable Hquid with a characteristic ethereal odor. It is miscible with other chlorinated solvents and soluble in common organic solvents. The compound was first prepared by Regnault about 1840.

Dicblorodifluoromethane (Freon 12) 175-71-8] M 120.9, m -158", b -29.8"/atm, 42.5"/10atm. Passage through saturated aqueous KOH then cone H2SO4, and a tower packed with activated copper on Kielselguhr at 200° removed CO2 and O2. A trap cooled to -29° removed a trace of high boiling material. It is a non-flammable propellant. 

In addition to the fluoroplastics and fluororubbers already described other fluoropolymers have been marketed. Polymers of hexafluoropropylene oxide are marketed by Du Pont (Krytox). These materials have a low molecular weight (2000-7000) and are either oils or greases. The oils are uses as lubricants, heat transfer fluids and non-flammable oils for diffusion pumps. The greases are also used as lubricants. They have good heat and oil resistance but it is said that explosions may result from contact with the surfaces aluminium or magnesium cuttings. 

Perchloroethylene is a clear, dense, non-flammable volatile chlorinated solvent. It is widely used for dry cleaning small quantities are used in adhesives and cleaning agents. It is miscible with organic solvents but only slightly soluble in water. Relevant physical properties are given in Table 5.50. 

Trichloroethylene is a colourless non-flammable chlorinated hydrocarbon liquid. It is mainly used for degreasing of metals in the engineering and electrical appliance industries other outlets are as a solvent in inks, in dry-cleaning, in varnishes and adhesives, and as a solvent in the extraction of fats and oils. Relevant physical properties are given in Table 5.51.

Liquid oxygen is pale blue, slightly heavier than water, magnetic, non-flammable and does not produce toxic or irritating vapours. On contact with reducing agents, liquid oxygen can cause explosions. 

Liquid earbon dioxide produees a eolourless, dense, non-flammable vapour with a slightly pungent odour and eharaeteristie aeid taste . Physieal properties are given in Table 8.5 (see also page 277). Figure 8.1 demonstrates the effeet of temperature on vapour pressure. 

The gas is non-flammable, and is used for inert gas purging. Because it is 1.5 times heavier than air it may accumulate at low level. The general handling precautions are those in Table 9.3.

It is a non-flammable eolourless gas whieh is twiee as dense as air, and slightly soluble in water forming sulphurous aeid. It is readily liquefied as a gas under its own vapour pressure of about 35 psig (2.4 bar) at 21°C. Figure 9.11 depiets the effeet of temperature on vapour pressure Table 9.26 lists the physieal properties. Cylinders tend to be proteeted against over-pressurization by metal plugs melting at about 85°C.

The catalyst is formed by reaction of HF on SbClj. The Freons have a unique combination of properties which make them ideally suited for use as refrigerants and aerosol propellants. They have low bp, low viscosity, low surface tension and high density, and are non-toxic, non-flammable, odourless, chemically inert and thermally stable. The most commonly used is CF2CI2, bp, —29.8°. The market for Freons...

Tri-n-butyl phosphate, ( -C4H9)3P04. This solvent is useful for the extraction of metal thiocyanate complexes, of nitrates from nitric acid solution (e.g. cerium, thallium, and uranium), of chloride complexes, and of acetic acid from aqueous solution. In the analysis of steel, iron(III) may be removed as the soluble iron(III) thiocyanate . The solvent is non-volatile, non-flammable, and rapid in its action.
