Organic matter? In chemistry, paraffin is the common name for a mixture of solid higher alkane slippery hydrocarbons, a mixture of hydrocarbons with a carbon atom number of about 18 to 30, and the main components of the air-delay are linear alkanes, as well as a small amount of alkanes with individual branched chains and monocycloalkanes with long side chains. Paraffin does not react with common chemical reagents, but it can be burned with a bucket slippery burn.

It is an organic substance containing the element ch.

Paraffin wax is not pure. Paraffin wax is a mixture. 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. It is a kind of petroleum processing products, mineral wax and petroleum wax. <

Paraffin wax is not pure. Paraffin wax is a mixture. Paraffin wax is a mixture of hydrocarbons extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils, and the main component is solid alkanes, odorless and tasteless, white or light yellow translucent solid.

Paraffin wax is amorphous, but has a distinct crystalline and mesosystemic structure. It is a kind of petroleum processing products, mineral wax and petroleum wax.

There are only paraffin wax components and nothing else. The composition of candles and their combustion products: Candles are usually manufactured from paraffin. Paraffin is a mixture of several higher alkanes, mainly n-dodosecane (C22H46) and n-octadecane (C28H58), containing about 85 carbon elements and 14 hydrogen elements.

Stearic acid (C17H35COOH) is also often added to candles to improve softness. Paraffin wax is a type of mineral wax and a type 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. Candles are an everyday lighting tool

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

A mixture of hydrocarbons with a carbon atomic 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, insulation of electrical components, improving rubber aging resistance and increasing flexibility, etc.

It can also be used for oxidation to generate synthetic fatty acid manuscripts.

The physicochemical properties of paraffin wax are as follows:

1. Physical properties.

1. Also known as crystalline wax, it is usually a white, odorless waxy solid, which melts at 47 °C-64 °C and has a density of about .

2. Paraffin is soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha and other non-polar solvents, insoluble in water and methanol and other polar solvents. Pure paraffin wax is a good insulator with a resistivity of 1013-1017 ohm·m.

2. Chemical properties.

1. The carbon atom number of paraffin wax is about 18 30 hydrocarbon mixture, 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%).

2. Paraffin does not react with common chemical reagents, but it can be burned. Catalytic cracking reactions can occur industrially.

3. The chemical activity of paraffin wax is low, neutral, chemically stable, and does not interact with acids except nitric acid and alkaline solutions under normal conditions.

1. The main raw material of candle is paraffin, paraffin is prepared from the wax-containing fraction of petroleum by cold pressing or solvent dewaxing, and is a mixture of several high-grade alkanes, mainly n-docadene (C22H46) and n-octadecane (C28H58), containing about 85 carbon elements and about 14 hydrogen nucleo-known elements. The added excipients are white oil, stearic acid, polyethylene, flavor, etc., among which stearic acid (C17H35COOH) is mainly used to improve softness, and the specific addition depends on what kind of candle is produced.

2. When the candle is burned, the products of n-docadecane and stearic acid combustion are carbon dioxide and water. The chemical equations for the reaction are 2C22H46 + 67O2 44CO2 + 46H2O and C17H35Cooh + 26O2 18CO2 + 18H2O.

3. When the candle is lit, the initial flame is smaller, and gradually becomes larger, and the flame is divided into three layers (outer flame, inner flame, and flame center). The flame core is mainly candle vapor, the temperature is the lowest, and the inner flame paraffin burns inadequately, and the temperature is higher than that of the flame core.

4. Because there are some carbon particles, the flame is the brightest, the outer flame is in full contact with the air, the combustion is sufficient, and the temperature is the highest, therefore, when a match stem is quickly put into the flame, about 1 second later, the match stem contact with the outer flame part will first turn black.
