Electroless Copper and Nickel-Phosphorous Plating

In the Metal Finishing Guidebook Directory (1997), in the electroless plating chapter (page 412), J.Henry gives explanation about electroless copper (page 419). Then the author talks about Quadrol reduced bath which are faster than the conventional baths and they do not use formaldehyde.

The question is : What is Quadrol or at least what is its scientific name so I can do some bibliographic research about.

If they do not use formaldehyde what is the reducing agent?

Thank you in advance

Quadrol is ethylenediamine.

Yes,

Quadrol is a ethylenediamine but it has so many variances to its name. Truly, the only proper way to find this chemical is by using its chemical abstract (CAS #102-60-3). I am the air emissions specialist at my facility and in order for me to determine the emissions from our plating tanks, I needed some background information on this chemical (i.e. boiling point, vapor pressure, etc.).

I had luck finding it in The "Merck Index" [link is to product info at Amazon] (11th edition) under the name "Entprol". I also know that one of the manufacturers of Quadrol is BASF Corporation in Germany. The chemical family Quadrol belongs to is the propoxylated amine family. I hope this helps out your research.
