WebThe solid wax will start to melt somewhat below 51 °C during heating, and the liquid wax will start to freeze somewhat above 65 °C during cooling. How far from the given temperatures it melts or freezes will depend on the width of the molecular weight range of the wax. WebWax Problems and Use of Solvents in the Oil Industry Most of the commercial wax inhibitors tested can reduce the deposition of paraffin with low molecular weight (≤C34 ), but have little effect on high molecular weight paraffinic wax (C35 –C44 ) [82]. Wax deposition in oil production flow mainly consists of C7 paraffin.

Paraffin wax is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C (115 and 154 °F), and a density of around 900 kg/m . It is insoluble in water, but soluble in ether, benzene, and certain esters. Paraffin is unaffected by most common chemical reagents but … See more Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room … See more Paraffin wax was first created in 1830 by German chemist Karl von Reichenbach when he attempted to develop a method to efficiently separate and refine waxy substances naturally … See more 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. The modification is … See more • Oligomer • Ozokerite See more The feedstock for paraffin is slack wax, which is a mixture of oil and wax, a byproduct from the refining of lubricating oil. See more People can be exposed to paraffin in the workplace by breathing it in, skin contact, and eye contact.
