At the end of the day I have to separate the salute and measure it. Up until now, I have been using a constant temperature oven, set a about 65 degree Celsius (evaporation temp of DCM). The exhaust DCM is expelled into the atmosphere and the dried salute is then cooled down and measured. I want to replace the oven with a rotary evaporator.

Sulfuric Acid Process | KBR

Different evaporator types can be used. For larger water evaporation capacities, multi-step evaporator systems are often used for energy saving purposes. The vapors of one step are used as heating agent for another process step. Medium Concentration. This process is used to concentrate sulfuric acid from 70 wt% up to 85 wt%.

Rapid and efficient diazotization and diazo coupling .

A convenient, rapid, one-pot method for the synthesis of azo dyes has been developed by the sequential diazotization–diazo coupling of aromatic amines with NaNO 2, silica sulfuric acid and coupling agents under solvent-free conditions at room temperature.Using this method, several types of aromatic amine, containing electron-withdrawing groups as well as electron-donating groups, were .

How do you maintain rotary evaporator equipment? The evaporator and its accessories can be maintained in a variety of ways in the lab. Keep these in mind as they are the key to implementing a properly functioning piece of equipment: Glass: Use a dilute sulfuric acid wash to clean the glass if it has serious substrate or dirt on it.

Sulfuric Acid Resistant Alloys

Sulfuric Acid Resistant Alloys

Hastelloys B and D were developed for handling sulfuric acid under very severe conditions, and they find use particularly in acid evaporators where dilute sulfuric is concentrated to about 65%. Alloy B is more resistant to boiling sulfuric up to about 60%, while D is employed chiefly over 60% concentration.

Does sulphuric acid evaporate over time? : chemistry

Does sulphuric acid evaporate over time? : chemistry

Sulphuric acid has a very low vapour pressure, so it barely evaporates at all. Now, the MARQUIS reagent has another component, which is formaldehyde. Formaldehyde does easily evaporate and can reversibly form a white polymer when it condenses. This polymer, paraformaldehyde, can be just as dangerous as the formaldehyde itself, so treat it .
