Very nice work Magpie! Good that the melting point is correct also.

In the start of this thread a gentleman asked if some material was restricted or "illegal" & the logical response made that material didn't exist on List 1 or List 2 chemicals. However there are more than the DEA List 1 & 2.
There is a DHS "List of Watched Materials" which I once tried to post but the damn thing was over 2Mb (compressed even as text!) so I couldn't put it up. In this discussion another individual made the remark that the material in question didn't appear to be a precursor to a chem-wep, etc. And there is where the issues become complex. The DHS list includes some esoteric materials that many would not consider as being significant yet are so in lab or plant-level production of items that are far from common.
The DHS list does not appear to have threshold amounts. In some materials the level of toxic utility is high enough that such a thing is immaterial. The DEA realized this when dealing with micro-gram level dose applications and changes were made. DHS never approached their agenda with threshold-levels in mind.
Because of their annoyingly secretive agenda; INTERPOL may have a list of watched materials (it may be where the DHS list was drawn from). However I was unable to find international organizational restrictions on chemicals or apparatus other than United Nations agreements, etc....
However, the level of discussion is out there & bold!

Chemical & Engineering News certainly is aware of restrictions growing internationally.

Do not have ANYTHING to do with Interpol! ( www.interpol.int ). They are as corrupt and Fascist as hell, out to frame as many people as they can with false charges in order to get promotion and justify their excessively costly existence! Interpol was founded around 1930 in Vienna, Austria, a country which then had its own home-grown Fascist régime (and still has a very right-wing government); and after the Anschluss of 1938 when the country was annexed by Nazi Germany, Interpol was run by the Nazi Gestapo until 1945!

Many of the international arrest warrants indiscriminately issued by Interpol, on request from various governments, are for what amount to alleged purely political offenses. In New Zealand, there is a political refugee from Algeria, Ahmed Zaoui, who was jailed for several years before being released and given asylum, because of a false arrest warrant delivered by Interpol on request from the Algerian Government, a dictatorship which alleged that he was wanted on criminal charges that turned out to be false and politically inspired.

This sort of thing is a good reason for national Constitutions or Bills Of Rights to be amended to prevent a country's own nationals from being extradited for any reason for alleged offenses committed in foreign countries, because of the danger that such allegations of offenses could be politically-inspired. This is already the case with France, Russia, most other eastern European countries, most Latin American countries, and several Asian countries including China and Vietnam. But this is, unfortunately, not the case with the UK, where the alleged "UFO hacker" Gary MacKinnon is still in grave danger of extradition to the U$A, a country he has never visited, for allegedly hacking NASA's website, based on a server in Virginia, to hunt for suppressed UFO-related information.

In the case of the U$A, the DOJ takes it upon itself to arrest and try U$ citizens for alleged offenses committed in foreign countries, which because of the difficulty of getting witnesses and material evidence out of foreign countries for use in U$ Courts (it would be impossible for a foreign Court to be induced to make such orders except for war crimes trials) could result in huge miscarriages of justice. If accused U$ citizens are also tried and jailed in the foreign countries in which they are alleged to have committed offenses, double jeopardy could result on deportation back to the U$A after serving jail sentences overseas.

I just ran a melting point test on my hotbench, and the phtalic anhydride provided by Jor has a melting point of 193 degrees centigrade. So it is also phtalic acid. Pretty needles though when it melts and partly vaporizes.



It could be that the purpose of your life is only to serve as a warning to others.

Hello Gruson! So you are the 3rd person now reporting that their purported phthalic anhydride is actually phthalic acid. So what gives with this. I didn't find my phthalic anhydride to be particularly hygroscopic.

Phthalic anhydride is supposed to be so much cheaper than phthalic acid. You would think it wouldn't be so hard to find.
