FAQs

Solutions of problems

A frequently asked questions (FAQ) forum is often used in articles, websites, email lists, and online forums where common questions tend to recur, for example through posts or queries by new users related to common knowledge gaps. The purpose of an FAQ is generally to provide information on frequent questions or concerns; however, the format is a useful means of organizing information, and text consisting of questions and their answers may thus be called an FAQ regardless of whether the questions are actually frequently asked.

What are fine and specialty chemicals?

Fine chemicals are substances that are produced by the process of complex syntheses and possess an assurance of pureness. Specialty chemicals is a broad term that generally refers to chemicals that are used for uses where the effects are the most important thing.

What are specialty chemicals companies in India?

What is EDC HCl?

Alternate Names: EDC hydrochloride is also known as (3-Dimethylamino-propyl)-ethyl-carbodiimide Hydrochloride. Applications: EDC hydrochloride is a water-soluble carboxyl activating agent, which is used to facilitate the formation of amide bonds. The CAS number is 25952-53-8. Purity >98 percent Molecular weight: 191.70.

What is EDC in chemistry?

Chemical compound 1-dichloroethane often referred to as ethylene dichloride (EDC) is a hydrocarbon with a chlorinated structure mostly used in the production of the monomer vinyl chloride (VCM chloroethene) which is the main precursor to PVC production. It is a transparent liquid that has an odor reminiscent of chloroform.

How do you remove EDC from a reaction?

If it’s water-soluble, you can reverse it and wash the compound with base, so that the EDC is organically soluble and eliminate it. If the compound you’re looking to use is sensitive to acid and base and you are unsure, try an alternative to coupling that isn’t diimide such as mixed anhydride as well as an acid chloride.

Why is TEMPO a stable radical?

The stable nature of free radicals that is present in TEMPO can be explained by the existence of large substituent groups that prevent reactions of free radicals with different molecules. TEMPO as well as its derivatives can be used principally to oxidize primary secondary and primary alcohols.

What is TEMPO mediated oxidation?

The TEMPO-mediated process of oxidation of native celluloses, on contrary, is a surface phenomenon that occurs when anionic carboxylate groups become functional groupings on the surfaces of solid cellulose.

What is the Tempo oxidation of cellulose?

This is a regioselectivity modification of the crystalline native microfibrils made of cellulose. It also permits the creation of anionic carboxylate groups that have very high densities on the microfibril surface.
