What is the boiling point of wax? What is the boiling point of paraffin?

The boiling point of wax is high, mostly above 300, and the melting point of wax is two grades, the first melting point is 74 78, and the melting point of the second grade is 66 68.

The freezing point of the wax.

All are relatively high, between 38 and 90. A lower iodine value (1 15) indicates unsaturation.

Lower than neutral fat.

Waxes generally refer to fatty acids, monovalent or divalent lithools, and oily substances with higher melting points in a narrow sense; In a broad sense, it usually refers to substances such as oils and fats that have certain similar properties.

Wax does not have a fixed melting boiling point, only a range.

Paraffin oil is composed of saturated components of paraffin hydrocarbons and naphthenes, containing trace amounts of aromatic hydrocarbons, tasteless, odorless, colorless transparent viscous liquid, chemically stable, heated and melted, burned and decomposed in case of high heat, boiling point 300 550 degrees.

Waxes are esters composed of high-carbon fatty acids and high-carbon fatty alcohols. Their boiling point is high, mostly above 300, and the melting point of wax is two grades, the first melting point is 74 78, and the second melting point is 66 68.

The wax has a fixed melting point, it is a hybrid crystal, and the chaotic arrangement of molecules can affect the rise or fall of the melting point.

Generally speaking, it's 66 to 78 degrees.

Only crystals have boiling and freezing points.

Paraffin wax is amorphous.

There will be no boiling point.

Wax is amorphous.

There is no fixed melting boiling point.

The melting point of wax: 47 degrees Celsius to 64 degrees Celsius. Wax is a solid that is insoluble in water and softens when the temperature is slightly higher and hardens when the temperature drops.

The biological function of wax is to act as a protective layer for the organism to the external environment, which is present on the surface of **, fur, feathers, plant leaves, fruits, and the exoskeleton of many insects.

Paraffin: Paraffin, also known as crystalline wax, is a non-polar solvent soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha, etc., insoluble in polar solvents such as water and methanol.

A mixture of hydrocarbons with a carbon atom number of about 18 30, the main components are linear alkanes (about 80% 95%), and a small amount of alkanes with individual branched chains and monocyclic naphthenes with long side chains (the total content of the two is less than 20%). Paraffin wax is a wax paste prepared by solvent refining, solvent dewaxing or wax freezing crystallization, pressing and dewaxing obtained from the lubricating oil fraction obtained by distillation, and then deoiled and supplemented with refined flake or needle crystals. According to the degree of processing and refinement, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.

Each type of wax is divided into different varieties according to the melting point, generally every 2, such as 52, 54, 56, 58 and other grades. Crude paraffin wax has a high oil content and is mainly used in the manufacture of matches, fiberboard, tarpaulin, etc. Fully refined paraffin wax and semi-refined paraffin wax are widely used, mainly used as components and packaging materials for food, oral drugs and some commodities (such as wax paper, crayons, candles, carbon paper), coating of baking containers, fruit preservation, electrical component insulation, improving rubber aging resistance and increasing flexibility, etc.

It can also be used for oxidation to produce synthetic fatty acids.

Wax does not have a fixed melting boiling point, only a range.

1. Waxes are esters composed of high-carbon fatty acids and high-carbon fatty alcohols. Their boiling point is high, mostly above 300 degrees, the melting point of wax is two grades, the first melting point is 74 degrees to 78 degrees, and the melting point of the second type of cavity dismantling grade is 66 degrees to 68 degrees.

2. Paraffin oil is composed of saturated components of paraffin hydrocarbons and naphthenes, containing trace amounts of aromatic hydrocarbons, odorless, odorless, colorless transparent viscous liquid, stable chemical properties, heated and melted, burned and decomposed in case of high heat, with a boiling point of 300 to 550 degrees.

Paraffin wax is amorphous, and it does not have a fixed melting point.

Paraffin is a mixture of hydrocarbons, so it does not have a strict melting point like pure compounds. The so-called paraffin wax melting point refers to the temperature at which the stagnation period occurs for the first time on the cooling curve of the paraffin specimen that has been cooled and melted under specified conditions. All kinds of wax products require paraffin wax to have good temperature resistance, that is, it does not melt or soften and deform at a specific temperature.

The main factor affecting the melting point of paraffin is the weight of the fraction of the selected raw material, and the paraffin wax coming out of the heavier fraction has a higher melting point. In addition, the oil content also has a great influence on the melting point of paraffin, and the more oil in paraffin, the lower its melting point.

Paraffin wax is amorphous and has no fixed melting and boiling points.

Paraffin wax is a mixture of hydrocarbons extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils, the main component is solid alkanes, odorless and tasteless, white or light yellow translucent solid. Paraffin wax is amorphous but has a distinct crystalline structure. There is also artificial paraffin.

Paraffin wax is a kind of petroleum processing product, a kind of mineral wax, and a kind of petroleum wax. It is a sheet or needle-like crystal obtained from the lubricating oil fraction obtained from ** distillation by solvent refining, solvent dewaxing or wax freezing crystallization, pressing and dewaxing to obtain wax paste, and then solvent deoiling and refining. It is used to make high-grade fatty acids, high-grade alcohols, matches, candles, waterproofing agents, ointments, electrical insulating materials, etc.

There are many common types of waxes, and different kinds of waxes have different melting points. The melting point of paraffin wax is 7-63, the melting point of polyethylene wax is 102-115, the melting point of EVA wax is 93-100, the melting point of PP wax is 100-135, and the melting point of special industrial wax is about 150.

Wax, produced by animals and plants, or the oil contained in Bi Ge oil, coal and oil shale, is mostly solid at room temperature, plastic, combustible, easy to melt, and insoluble in water.

Wax, used as a waterproofing agent, can also be used as a candle. Candles originated from torches in primitive times. Beeswax, which appeared around the 3rd century BC, may have been the prototype of candles.

The original high-quality materials of candles include yellow wax, white wax and so on. Yellow wax is beeswax, and white wax is the wax secreted by termite insects. The use of white ash is generally believed to have started in the Tang Dynasty, and some people have researched that it began in the Han and Wei dynasties.
