Semi Refined Paraffin Wax
American Society for Testing and Materials (ASTM) D721-06, is the method for testing the oil in Semi Refined Paraffin Wax . The technique is slow (the process takes about 2 hours) and requires technical skills and the use of hazardous solvents. The Oil in Wax NMR method is a ratio method so the sample does not need to weigh. Generally , the Oil in Wax NMR method can exploit two different hardware configurations to optimize for two ranges of oil content. That dependent on the sample and/or user requirements:
- 2% and above: rapid measurement using a standard with 10-mm diameter samples and sample pre-conditioning at low temperature (usually;5 °C).
- 0.1% to 2% oil: low detection limit measurement using an with 10-mm diameter samples and equipped with a low-maintenance , fluid-cooled temperature-regulated probe (usually ;5 °C or less).
Also Experience shows that different types of wax may have different physical , and consequently NMR, properties which may we need to calibrate separately.
For example,the results for a set of waxes which we separate that into three different calibrations depending on the oil content and wax type. The MultiQuant software is versatile. We can optimize Calibrations after the reference samples that we measured. And do not have to measure again to produce different calibrations. It is good practice to re calibrate the instrument regularly, especially if new wax products we need to measure.
In addition a flammable, whitish, translucent, waxy solid consisting of a mixture of saturated hydrocarbons, obtained by distillation from petroleum. Or shale and we use in candles, cosmetics, polishes, and sealing and waterproofing compounds.
Properties of Semi Refined Paraffin Wax
Semi Refined Paraffin wax,colorless or white, somewhat translucent, hard wax consisting of a mixture of solid straight-chain hydrocarbons ranging in melting point from about 48° to 66° c (120° to 150° f). Furthermore Paraffin wax is obtained from petroleum by dewaxing light lubricating oil stocks. We use that in candles, wax paper, polishes, cosmetics, and electrical insulators. However It assists in extracting perfumes from flowers, forms a base for medical ointments, and supplies waterproof coating for wood. In wood and paper matches, it helps to ignite the matchstick by supplying an easily vaporized hydrocarbon fuel.
Also Paraffin, or paraffin hydrocarbon, is also the technical name for an Alkane in general. But in most cases it refers specifically to a linear, or normal Alkane whereas branched. Or Iso Alkanes are also called ISO paraffin. It is distinct from the fuel known in the United Kingdom, Ireland and South Africa as paraffin oil or just paraffin. Which we call Koresen in most of the u.s., Canada, Australia and new Zealand.
In addition we first produce Paraffin wax commercially in 1867, less than 10 years after the first petroleum well we drilled. Paraffin wax precipitates readily from petroleum on chilling. Technical progress has served only to make the separations and filtration more efficient and economical. Purification methods consist of chemical treatment, de-colorization by adsorbents, and fractionation of the separated waxes into grades by distillation, recrystallization, or both. Crude oils differ widely in wax content.
