Process for coloring paraffin wax and the like
coloring paraffin wax which is for candles and waxy paper and the like, the coloring processes in present use have been unsatisfactory .
they are relatively and the colors so fade, in other words, these processes do not always produce 10 colors fast to light.
At present it is the practice to melt the paraffin, wax and intermix therewith the especially prepare dyes. which have been so as to be soluble in the melted paraffin.
Sults are obtain by using a slight excess of the fatty acid, in that a better color is thus produced in the melted paraffin.
The pure triethanolamine is represented by the formula:
the commercial grade contains approximately seventy-five to eighty per cent triethanolamine, twenty to twenty-five per cent.
As mention, the commercial triethanolamine combines with the fatty acid to form a soap , which is the case of stearic acid produces a substantially transparent, solid soap, soluble in organic liquids, specifically melted paraffin wax
Paraffin wax having low electrical conductivity and method of coating glass therewith
This invention relates to paraffin waxes having low electrical conductivity even under conditions of high humidity. More particularly, the invention is concern with a composition of matter comprising a paraffin wax having incorporate.
The paraffin wax is any one of the well-known hydrocarbon waxes having adequate softening points, for example, softening points . well above room temperature, for instance, around to 0. Generally, the paraifn use in the practice of the invention , comprises a solid paraffin wax which may or may not .
Paraffin wax composition
The methods of separating paraffin wax from crude petroleum products, such as by distillation, chilling with filtering or centrifuging are well. Various methods of paraffin wax purification, such as treatment with sulfuric acid and fullers earth are also well.
Although this purification helps to produce more stable paraffin waxes, initially free from odor, taste, and color. it is not effective enough to prevent subsequent oxidative deterioration which has been troublesome to industrial users of paraffin wax.
One of the most wide applications of paraffin wax is in the coating industry wherein hot wax baths are for waterproofing, treating, impregnating or sizing paper . similar products, and wherein wax is to provide a protective coating for materials of all kinds.
Besides the formation of objectionable odors and an increase in color and acidity, oxidation brings about a lowering of melting point and tensile strength. and an overall deterioration of valuable properties such as hardness and the like, of the wax. Moreover, when decomposition occurs, much wax is lost through volatilization .
Purification of paraffin wax
The present invention relates to the purification or separation of mixtures of fatty or mineral oils or distillation or destructive hydrogenation products of coal .
and the like especially of n carbonaceous materials containing substantial amounts of paraffin wax. For purification or separation of mixtures of fatty or mineral oils or distillation or hydrogenation products of coals or other carbonaceous materials solvents , consisting substantially of a tomato 0!
The lower alcohols oi the fatty series or mixtures of several formates have already been employed.
Preparation of paraffin wax for utilizing its thermal expansion properties
This invention relates to preparation of paraffin wax for utilizing its thermal expansion properties. More particularly, the invention relates to the pre-treatment of parafiin wax for the purpose of improving its capacity to impart motion to mechanisms by expansion of the wax.
The expansion properties of wax may also be utilize for the forming of metal products.
paraffin wax, pre-treat as hereinafter describe, may be encase in a high pressure cylinder and heat to actuate reciprocating means in the cylinder for operating dampers, valves, shutters, pumps and other devices.
The thermal expansion of commercial paraffin wax has been utilize heretofore for imparting motion to mechanisms, such, for example, as shown in us.
forming of metal products, we have discover that the composition of waxes can be alter and the thermal expansion properties of the waxes thereby substantially improve.
By experiments which will be describe hereinafter, we have determined that paraffin wax contains dissolve hydro-carbon gases and that molten paraffin wax.
absorbs oxygen from the air. Further, we have ascertain that the presence of these gases in the paraffin wax heretofore use to actuate mechanism lessens .
the expansion and pressure producing capacities of the wax when heat, and results in a gas cushion which resists the return movement of the pressure actuate means.
