    These guys want $98.10 US for 10 g of the stuff, it sounds like a synthesis project. Snapshot, you said you have long cold winters and need a project!!..Good luck...EC

    It certainly cannot cost that much or the E6 first developer price would be out of sight. What does Kodak sell it for?

    They are a lab chemical place and always get huge dollars for even common chemicals like sulfite...EC

I am using the e-6 bleach as my current C-41 bleach, and otherwise I have stuff to spare. I think that I have 3 or so 1 gallon concentrates of E-6 first developer; so if it is just the first dev developing agent that has you stumped, there is a work around at hand. I too mix from scratch, and have done Watkins Chromebrew in the past, so I know what you are up against.

    I am making a run downtown tomorrow and sunday to drop off my kids for a weekend away at thier aunts, so if you don't have access to a car, give me a call and perhaps we can set a drop off up. I will PM you with my contact details, but my subscription has expired, and the last time it did so the credit card script could not handle me not having a US state as part of my address, so I am not sure if that is going to work yet. If no PM in the next short while, post your interest or not back here. Mike.
    I'm definitely interested. Let me know what you want me to do. Thanks!

    Unforutnately, I'm not a chemistry wiz or even semi-skilled. If anyone can offer any input on how to make the stuff, I will definitely appreciate it. I'm wondering if the libraries here in the GTA have anything that can be useful?

    High snapshot, and all others !!

    Google around for cas: 21799-87-1

    You will find various supplier for potassium hydroqinone monosulfonate. Most of them im China / Hong kong or wherever.

    But not all of them. Follow the link below:

    http://newsearchch.chemexper.com/che...=brandqtyoffer

    This stuff is distinctly more expensive than hydroquinone, I paid 55 Euro (~75 Dollar) for one Kg, but the main difficulty will be to convince the distributors to sale small (1 kg) ammounts to a private Person.
    On the other hand, if you get a "real" person on the telephone, it will work propably, (hopefully). At least this is the way it works for me, they all want to earn some money at the end...

    Regards,
    Stefan

    Evidiently, you can create the the HQMS with sodium sulfite, hydroquinone and hydrogen peroxide.

    Hydroquinone Monosulfonate, Sodium

    25.0g of sodium sulfite, 11.0g of hydroquinone and 10ml of hydrogen peroxide (40% solution) in 500ml of water.

    This should get me what I need. Obviously, I'll have to balance out the first developer formula to get the correct pH and results.

    I would like to thank a friend and fellow APUGers, PE especially, for helping out.

    I've got all of that but the 40% H2O2. That is dangerous stuff. If you can get it, be very very careful of it. It is a very powerful oxidant.

    The 3% might work just as well here seeing as there is so much water involved. The peroxide is being diluted to 4%, so that is 4 grams of H2O2 itself. All you need is 133 ml of 3% H2O2 and 366 ml of H2O to reformulate and make things come out even.

    That should work, but addition method could be important.

    Yes, I was concerned about the H2O2 as well. In fact, you might not be able to buy H2O2 in Canada without a permit. I will call my local chemical supplier and see if what hoops I need to jump through. Otherwise, I will use store bought 3% solution.

    I have about 2 Kg of HQ here. I may give this a crack.

    However, the hard part will be purification of the material and making a solid of it. You cannot be sure of what you have from any organic reaction until you recrystallize it.
