N-Pentadecane 99%
N-pentadecane (also known as Pentadecane) is a straight-chain alkane with a carbon chain containing 15 carbon atoms. The following is an introduction to the properties, uses, preparation methods and safety information of Pentadecane:
Properties:
- Pure Pentadecane is a colorless liquid with very low volatility and a slight special odor.
- Pentadecane is a non-polar compound that is insoluble in water but soluble in organic solvents such as ethanol, chloroform and carbon disulfide.
- It has good chemical stability and can exist stably at high temperatures.
Uses: It can make products have a smooth touch.
- Pentadecane is also an important organic solvent and is often used in the manufacture of coatings, inks and adhesives.
- It is also commonly used in the preparation of lubricating materials such as synthetic lubricants and gasoline additives.
Preparation method:
- Pentadecane can be prepared by cracking or hydrogenation of alkanes. Among them, alkane cracking usually adopts catalytic cracking or thermal cracking methods, while hydrogenation reactions are carried out under appropriate conditions using catalysts.
Safety information:
- Pentadecane is highly flammable and may catch fire or explode if exposed to open flames or high temperatures.
- When handling pentadecane, necessary safety measures should be taken, such as equipping explosion-proof equipment and wearing protective gloves and glasses.
- Avoid inhaling pentadecane vapor and operate in a well-ventilated area.
- When using and storing pentadecane, keep away from fire and oxidants to prevent dangerous situations.
Chemical properties
Stability: Good chemical stability. Because it belongs to a saturated hydrocarbon structure, it is relatively tolerant to general acid, alkali, oxidants and other chemical reagents at room temperature and pressure, and is not prone to chemical reactions. Usually, only under special conditions such as high temperature, light, strong oxidants and specific catalysts, the carbon-hydrogen bond can be destroyed, which in turn triggers oxidation, cracking and other reactions, changing its chemical structure and properties.
Oxidation reaction: Under the action of strong oxidants (such as potassium permanganate, potassium dichromate, etc. under acidic conditions), oxidation reactions can occur and gradually be oxidized to oxygen-containing compounds, such as first being oxidized to corresponding alcohols, and then the alcohols can be further oxidized to generate compounds such as aldehydes, ketones or carboxylic acids. However, such oxidation reactions require strict control of reaction conditions, and the reaction rate is relatively slow, depending on factors such as the type and concentration of the oxidant and the reaction temperature.
Substitution reaction: Under conditions such as light or high temperature, the hydrogen atoms in its molecules can be replaced by halogen atoms (such as chlorine, bromine, etc.), and halogenation reactions occur to generate corresponding halogenated hydrocarbon products. As the reaction conditions continue to act, multiple substitutions may gradually occur to generate halogenated hydrocarbon mixtures with different degrees of substitution. This reaction has certain application value in organic synthesis and can be used to prepare some organic intermediates containing specific functional groups.
