Can't find Versene "T"

Q. Hi everyone. I have a problem finding Versene "T". Even Dow Chemicals doesn't know what that Versene is. It is from an old formulation for high throw (1 mil/hr) electroless copper plating bath. Can you help me find it or replace it.

Thanks in advance,

A. Versene is EDTA. It is a commercial name. I do not know what the T stands for but there are a lot of chemicals in this family. Degussa manufactures EDTA by the name of Trilon, they may help you in finding out what the T stands for. Sara

A. I just came across a ref. in regards to Versene "T". It is a mixture of EDTA and TEA.

Thanks to all,

A. I think the Hampton Chemical Co. in Nashua, NH used to produce this product. I do not know if they are still in business or were bought out by someone else.

Q. Not so much a contribution as another question - I'm trying to find out which of the many possible EDTA salts Versene 220 is.

Anyone have any ideas?

Thanks in advance

A. Langford and Parker, Analysis of Electroplating and Related Solutions [affil link on Amazon, ... on AbeBooks], has "EDTA.... it appears in industry under a series of trivial but useful synonyms such as Versene, Sequestrene, Trilon B, Chelaton 3 and Complexone III....."

So it may be just diamino-ethane tetra-acetic acid [on eBay or Amazon], disodium salt, (but it still could be a mixture). Have you tried searching for Versene in a search engine?

A. Versene 220 is same as Hampene 220 : 99%+ tetrasodium salt of EDTA.

Q. Hey everyone I have a question about this. I'm working with EDTA and want to find a way to break it down into its origanal components like with an oxidation reduction, but I don't know what to use or how to do it.

Thanks

Q. What formulation of EDTA is used in chelation therapy for metal toxicity and arterial disease?

Hello, Heidi. You probably found this page by searching for specific terms in a search engine, rather than by coming through 'the front door' of our metal finishing site. Anyone is certainly welcome to answer, but this site focuses on metal finishing so most of our readers probably know little about chelation therapy and arterial disease, I'm afraid. Sorry.

Q. I would like to know will sequestering agents such has Versene help in avoid iron contamination in nickel plating baths. This is being a serious problem.

A. I am just replying to a question. I found reference to this material in Modern Electroplating by Lowenheim →
Versene-T is sodium salt of ethylenediamene-tetraacetic acid . EDTA.

Abner Brenner used this in Electroless Copper as a preliminary solution for non-conductive substrates.
