What is chlorinated paraffin used for?
Chlorinated paraffins are used as plasticizers for polyvinyl chloride, as extreme-pressure additives in metal-machining fluids, as additives to paints, coatings and sealants to improve their resistance to chemicals and to water, and as flame retardants for plastics, fabrics, paints and coatings.
Is chlorinated paraffin poisonous?
(1976) report that chlorinated paraffins are “practically nontoxic” in humans with a probable oral lethal dose above 15 g/kg, or greater than 2.2 pounds, for a 70-kg person. Table 19–4 provides a summary of oral acute and short-term toxicity data for chlorinated paraffins.
How do you chlorinate paraffin?
Chlorinated paraffins are synthesized by reaction of chlorine gas with unbranched paraffin fractions (<2 % isoparaffins, <100 ppm aromatics) at a temperature of 80–100 °C. The radical substitution may be promoted by UV-light.
How do you remove chlorinated paraffin?
There is no cleaning compound available which forces the paraffin to float on the surface and allow for removal via an oil water separation system.
What are medium-chain chlorinated paraffins?
Medium-Chain Chlorinated Paraffins (MCCPs) are a mixture of chlorinated hydrocarbons with a chain length of 14 to 17 carbon atoms, and the same chlorine content range of 40-70%. SCCPs are commonly used as flame retardants and plasticizers in plastics, as well as lubricants and coolants for metal forming operations.
What is chlorinated oil?
Chlorinated paraffins are added to metalworking lubricants as extreme pressure additives. They actually react with the surface under conditions of high temperature and pressure to provide maximum lubrication. While they are excellent lubricant additives, they can be very difficult to remove.
How do you make chlorinated paraffin wax?
The raw materials required for manufacturing chlorinated paraffin wax are paraffin wax, chlorine, Sodium carbonate, activated carbon. Process of manufacturing: Paraffin Wax is melted in a vessel provided with steam jacket. The molten wax is charged to a glass lined chlorinator jacketed for steam heating.
How is chlorinated paraffin wax made?
Chlorinated paraffins are manufactured by the chlorination of n-paraffin or paraffin wax, normally in a batch process. The reaction is exothermic and leads to the generation of the by-product hydrochloric acid. After removing residual traces of acid, a stabiliser is added to produce finished batches.
What is paraffin C14?
Description. Sasol Chemicals C1416 Normal Paraffin is a high purity mixture of saturated alkanes in the C14 – C16 carbon range. It is high purity unhydrogenated paraffin. It is a clear, light yellow, oily liquid with a low viscosity. C1416 Normal Paraffin has an extremely low sulfur and nitrogen content.
How do you manufacture paraffin wax?
1 Manufacture. Paraffin wax is usually obtained by dewaxing refined lubricating oil stocks. Dewaxing processes usually employ a combination of chilling, filtration, and extraction by suitable solvents such as MEK or MIBK.
How do I get a CPW?
