Reaction equip

Reactor

  • Reaction is a kind of chemical change. Chemical change is to change 1 or more than 2 substances to different substance in the aid of heating or mixing.
  • Reaction has a very wide range, for example, metal oxidation and living things respiration. Also in industry, saponification, synthetic resins, perfume, fiber and pharmaceuticals. It is necessary in our life.
Ketene lamp apparatus

 To produce Ketene gas from acetone

How to operate
  • Charge some acetone in the flask (10) Heat up and reflux acetone. Expel air from the reaction tube (56) by acetone vapor completely.
  • 5 minutes later, starting heat up Nichrome wire. When the wire turns reddish brown color around 700 ℃ ~750 ℃, Ketene gas occurs. You could get Ketene gas from exit (48) with ethylene, carbon monoxide and methane.
  • Keep temperature carefully. Black smoke occurs when overheated. You have to operate in the draft. Ketene gas is poisonous gas, it has -56 ℃ boiling point.
  • With organic synthetic reaction, Ketene gas is used as acetylating agent in general. For example, when ketene is reacted with alcohol or acetic acid, it could be turned to acetic anhydride or acetic acid ester.
Dehydration reactor

 Multipurpose reaction and distillation apparatus

This apparatus could do combination experiments of Chemical reaction, dehydration reaction and distillation by this apparatus only.

When two compounds have nearly same bp, one of compounds is alcohol or aldehyde, ketene this apparatus could separate them by combination of esterification reaction, acetalization reaction and after that simple distillation.

Features
It does not need high performance distillation column if samples 'boiling points were very close or not.
  • Using this apparatus only.
  • It consists of zeolite dehydration membrane for dehydrate, so it does not need dehydration support solvent (example; toluene).
  • It uses reusable strongly acidic ion exchange resin for catalyst.
  • It has removable stainless steel basket inside for catalyst reuse.
  • It need not change vessel between reaction and distillation operation.
  • Easy to scale up to production plant.
  • For broad range of application.
  • Possible to cost down.
* This apparatus does not work for some of substances.
