Medium Or Material That CAN And CANNOT Be Used in Glass Reactor

As a commonly used experimental equipment, the reactor has a wide range of applications and scopes. It can be used in experiments and scientific research in many fields, such as chemistry, biology, pharmacy, etc., for various inorganic and organic synthetic reactions, mixing, dilution, dissolution, precipitation, extraction and other experimental operations. At the same time, the glass reactor also has the characteristics of simple operation, good transparency, corrosion resistance and high safety, which can meet the needs of the reactor in laboratory and industrial production. Therefore, chemical glass reactor plays an important role in laboratory and industrial production, and is widely used in various fields of research and experimental work.

When using a glass reactor equipment, improper operation or inappropriate substances may lead to equipment failure or shorten its service life. Therefore, it is necessary to pay attention to the selection of suitable media or materials when using glass reaction kettle to avoid damage to the equipment.

Media or materials that can be used in glass reactor kettle

Alcohol

 

Such as ethanol, methanol, etc., often used in organic synthesis reactions, such as esterification and etherification.

 

Alcohol is a kind of organic compound, and its molecular structure contains hydroxyl (-OH). Alcohols can be prepared by hydrogenation of hydrocarbons or other organic compounds with hydrogen under the action of catalysts. According to the number of carbon atoms connected to hydroxyl groups, alcohols can be divided into monohydric alcohols, dihydric alcohols, trihydric alcohols and so on.

Common monohydric alcohols include methanol (CH3OH) and ethanol (C2H5OH), which are widely used in organic synthesis, dissolution and extraction in laboratory and industrial production.

Diatomic alcohol refers to alcohol compounds containing two hydroxyl groups in the molecule, such as ethylene glycol (HOCH2CH2OH), which is widely used in the chemical field as solvent, lubricant, coolant, fire retardant and so on.

Tri-alcohols contain three hydroxyl groups, such as glycerol (C3H8O3), and are often used as solvents, thickeners and humectants.

Alcohol has many characteristics, such as strong polarity, easy to dissolve in water, and can react with many organic and inorganic substances. These characteristics make alcohols widely used in chemical synthesis, dissolution reaction, extraction, solvents and reaction media.

Ethers

 

Such as diethyl ether and dimethyl ether, which are often used in organic synthesis and dissolution reactions.

 

Ethers are a kind of organic compounds, whose molecular structure contains oxygen atoms connecting two carbon chains or hydrocarbon groups. The general chemical formula of ethers is R-O-R', where R and R' represent organic groups.

Ethers can be divided into the following categories according to the number and position of organic groups in their molecules:

Symmetric ether (symmetrical diether): Two organic groups are the same, such as diethyl ether (C2H5OC2H5).

Asymmetric ether (asymmetric diether): Two organic groups are different, such as methyl ethyl ether.

Aromatic ether: One or two organic groups in the ether are aromatic rings, such as phenyl ether (C6H5OC6H5).

Ether compounds are relatively stable in chemical properties. Common ethers such as diethyl ether and dimethyl ether are colorless liquids with low boiling point and good solubility. Ethers are widely used in laboratory and industry, including as solvents, extractants, catalysts, reaction intermediates and so on.

• Water: As a neutral medium, water is widely used in chemical synthesis, reagent preparation and other experiments.
• Acidic solution: Some weakly acidic solutions, such as dilute sulfuric acid and hydrochloric acid, can be used in glass reactors.
• Solution: Including various solutions, such as sodium salt solution, ammonia water solution, etc., which can be used to dissolve reagents or catalyze reactions.

Media or materials that cannot be used in glass reactors

1. Any reaction process in which acid and alkali alternate, because the glass reaction kettle may be corroded by acid or alkali.

The reaction process of acid-base alternation refers to a chemical reaction in which acid and base exchange components to produce salt and water. This reaction is called neutralization reaction, and its essence is that H+ and OH- combine to form water, or acid+alkali → salt+water. However, the reaction with salt and water is not necessarily a neutralization reaction.

When an acid meets an alkali, a neutralization reaction occurs, resulting in salt and water. This is because there are acidic and alkaline properties between acid and alkali, and their reaction can neutralize each other's properties and form neutral products.

Generally speaking, strong acid and strong base will react first, then weak acid and strong base, and finally weak acid and weak base. This is because strong acid and strong base have high ionization degree and fast reaction speed, and the produced salt and water are completely dissociated. However, the reaction speed of weak acid and strong base, weak acid and weak base is relatively slow, because their ionization degree is low, and the dissociation degree of salt and water produced by the reaction is also low.

2. Hydrofluoric acid or media or materials containing fluoride ions at any concentration and temperature, because they may react with the glass components in the glass reactor, resulting in equipment damage.

3. Any alkaline medium or substance with a PH value greater than 12 and a temperature higher than 80℃, because they may cause excessive stress to the glass reactor and cause equipment damage.

4. Any phosphoric acid medium or material with a concentration greater than 30% and a temperature greater than 180℃, because they may cause excessive stress to the glass reactor and cause equipment damage.

5. When the temperature changes sharply, the excessive stress will lead to porcelain explosion and damage the equipment. Therefore, attention should be paid to heating or cooling during use to prevent cold and heat accumulation.
