The first online PTC Tip of the Month newsletter was published here [http://phasetransfer.com/tip1.htm] in October 2002. This has been a labor of love for 20 years. (Please do not click on the links in the October 2002 issue since most of the links are inactive or go to expired Email addresses.)
An index of the first two years of the PTC Tip of the Month is shown here: [http://phasetransfer.com/tipmain.htm]. Most of the links on this page work and they include information that is valuable today!
We started the 16-page Phase-Transfer Catalysis Communications Newsletter in print, published and mailed quarterly at significant expense in September 1994, 28 years ago.
In one of the print newsletters in the early 2000’s, the back page promoted the “PTC Webinar Series” and had written in big letters “What is a Webinar” since that was a new term. In those days, the PowerPoint presentation was shown on the internet and chemical company customers had to hear the audio by phone on a special line that could handle 100 lines at significant expense to PTC Organics.
Times have changed!
What has stayed constant over the past 20 years is that Phase-Transfer Catalysis delivers LOW-COST HIGH-PERFORMANCE GREEN CHEMISTRY and that Marc Halpern of PTC Organics Inc. will continue to provide PTC process development services “forever.” Contact us to inquire about PTC training, PTC consulting, PTC contract research or PTC licensing.
