What is amberlyst catalyst?

Amberlyst A21, a neutral ion-exchange resin and a solid base, can catalyze the three-component reaction of aldehyde and malononitrile with various active methylene compounds at room temperature to synthesize a range of pharmaceutically important pyran annulated heterocycles.

What is amberlyst?

Amberlyst® 15(H) is a strongly acidic cation exchange resin used as a heterogeneous acid catalysis and is suitable for non-aqueous catalysis. It is used to determine the mechanism of phenol alkylation using density functional theory (DFT). It is widely utilized as a column packing material for HPLC analysis.

What is amberlyst a 21?

General description. Amberlyst A21 is a neutral ion-exchange resin and a solid base which catalyses three-component reaction of aldehyde and malononitrile with various active methylene compounds to synthesize a range of pyran annulated heterocycles.

Why is Amberlyst 15 a good catalyst?

An inexpensive material, Amberlyst-15 possesses unique properties such as environmental compatibility, nontoxicity, reusability, non-corrosiveness and chemical and physical stability — allowing for its versatile synthetic applications.

What should you do if you get amberlyst on your skin?

Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.

What does amberlyst 15 do?

Researchers offer a novel and highly sustainable method for the acylation of phenols and alcohols. They found that Amberlyst-15 is an active catalyst for the acylation of phenols and alcohols by means of acetic anhydride as an acylating agent at room temperature under heterogeneous conditions.

How do you regenerate Amberlyst 15?

If you use it as a cation exchanger, it is usually regenerate with 2-4 BV (the resin’s volume) of 3-7% HCl. To get a better regeneration rate, you need to put the resin into a column, the height of the column better not less then 500mm. Pass the regenerant from top to bottom in 1-2 hours.
