Customized distillation device, distillation tower, distillation column, distillation kettleBefore loading, the tower wall and packing must be cleaned. Usually, it is necessary to first wash with carbon tetrachloride and dichloroethylene, then heat treat with benzene once, rinse with distilled water, and dry before filling. When filling, take a small amount of filling from the top with a cow horn spoon or directly insert it with a glass rod. At this time, the tower should be tilted to avoid damage to the support frame caused by impact when vertically added. Afterwards, add a small amount of small filler multiple times and gently tap the tower body with a wooden rubber mallet while installing to avoid bridging. After filling, continue to vibrate and knock for a period of time until the filling position no longer moves down.

Customized distillation device, distillation tower, distillation column, distillation kettleA single-layer column can be wrapped with asbestos rope or electric heating wire outside the column body for insulation purposes. Insert a thermometer into the distillation head, connect the receiver to the lower part of the side tube, add the required mixed organic compounds for distillation to the distillation flask, and fully wet the inner wall of the tube and the surface area of the filling material. When heating, use an oil bath, water bath, or electric heating jacket. Do not use open flames to directly heat to prevent low boiling point substances from burning during distillation. When the distillation liquid enters the receiving flask, control the reflux ratio according to the requirements. After the experiment is completed, wait for the material to cool down before stopping the cooling water.

Principles and Applications:

Distillation tower is a tower type gas-liquid contact device. By utilizing the property that each component in the mixture has different volatility, that is, the vapor pressure of each component is different at the same temperature, the light components (low boiling substances) in the liquid phase are transferred to the gas phase, while the heavy components (high boiling substances) in the gas phase are transferred to the liquid phase, thus achieving the purpose of separation.

Suitable for the separation and purification of one or more organic mixtures in departments such as pharmaceutical research, petrochemicals, and chemical reagents in the food industry. For example:

1) Chemical industry: used for separating and purifying high-purity chemicals, such as organic solvents, dyes, insecticides, chemical reagents, etc.

2) Pharmaceutical industry: used for preparing high-purity drugs and intermediates.

3) Food industry: used for extracting and separating natural products, such as spices, pigment plant extracts, etc.

4) New material research and development: used to prepare new high-purity materials, such as high-purity metals, semiconductor materials, optical materials, etc.

5) Petrochemical industry: used for the separation and refining of petrochemical products, such as petroleum fractions, natural gas, and petrochemical grade water.

6) Biotechnology: used for separating and purifying biological products, such as proteins, Portuguese antibodies, etc.

Features:

The separation concentration is high, and under appropriate operating conditions, the separation concentration can reach PPM level.

The tower structure is streamlined and suitable for separating small and valuable materials.

The reflux ratio is precisely controlled, which is beneficial for exploring experimental adjustments.

Accurate temperature control is more conducive to adjusting experimental conditions.

It can be subjected to intermittent distillation or continuous distillation.
