Paraffin wax is brittle, and having a density of around 0.9 … Like paraffin waxes and micro-crystalline waxes, soft speciality waxes are produced by means of elaborate refining techniques such as distillation, crystallization (de waxing) and de-oiling during the processing of petroleum. Low-melt point paraffin (less than 130 degrees Fahrenheit) is used for container candles in jars, cups, or glasses. You’ll find soy wax with melting points going from 125 up to 160 degrees Fahrenheit. The tissue is then placed in paraffin wax for a number of hours and then set in a mold with wax to cool and solidify; sections are then cut on a microtome. [16][17], Paraffin wax was first created in 1830 by the German chemist Karl von Reichenbach when he tried to develop the means to efficiently separate and refine the waxy substances naturally occurring in petroleum. As you’ll see below, the market has plenty of different paraffin wax varieties – the goop in the wax to make it behave a certain way is what distinguishes these. Gel wax has a high melting point at around 180 degrees Fahrenheit. Most commonly, the slack wax is heated, mixed with one or more solvents such as a ketone and then cooled.

The branched properties result in a modified paraffin with a higher viscosity, smaller crystalline structure, and modified functional properties. Purification methods consist of chemical treatment, decolorization by adsorbents, and fractionation of the separated waxes into grades by distillation, recrystallization, or both. It is insoluble in water, but soluble in ether, benzene, and certain esters. It is a white or colorless soft, solid wax, with a typical melting point between about 47 °C and 64 °C (117°F to 147°F), begin to enter the liquid phase past approximately 37°C. The feedstock for paraffin is slack wax, which is a mixture of oil and wax, a byproduct from the refining of lubricating oil. The first step in making paraffin wax is to remove the oil (de-oiling or de-waxing) from the slack wax. Low Melting Point 48 Soft Paraffin Wax 48 Soft Paraffin Wax Introduction. Paraffin wax is combustible and has good dielectric properties. It assists in extracting perfumes from flowers, forms a base for medical ointments, and supplies a waterproof coating for wood. If you add it to candle wax it will usually melt a lower temperature. [3] Common applications for paraffin wax include lubrication, electrical insulation, and candles;[4] dyed paraffin wax can be made into crayons. In a histology or pathology laboratory, paraffin wax is used to impregnate tissue prior to sectioning thin samples of tissue. It is sold with various melt points, typically between 43-60 °C (other melting points are available on request) and has a boiling point above 370 °C. Crude oils differ widely in wax content. In industrial applications, it is often useful to modify the crystal properties of the paraffin wax, typically by adding branching to the existing carbon backbone chain. Maximum height for storage is 5 sacks for soft wax and 9 sacks for hard wax. Water is removed from the tissue through ascending strengths of alcohol (75% to absolute) and the tissue is cleared in an organic solvent such as xylene. ] it is soluble in ether, benzene and certain esters `` mineral.!
