I'm having a really hard time locating relevant refs for this procedure. I am interested in using potassium dichromate and concentrated H2SO4. I know the problem is I don't yet understand the more subtle language used in theoretical write ups and even patents. I really don't have an aversion to reading, I just can't find what I need to read. I did UTFSE and not surprisingly the thread about Caro's acid is the only one that showed a hit, even though the word chromic only appears in an old rhodium document about Caro's acid, the author's name was Chromic. It is sheer coincidence that Caro's acid and chromic acid are somewhat used along the same lines as a strong oxidizer.

I found this, but would still appreciate any advice or critiques of these methods as none of them make use of the chemicals I have.

The Preparation Of Chromic Acid

Chromic acid (H2CrO4) is produced by two or three methods. In one, 2 parts (by measure) of a cold saturated solution of bichromate of potassia are mixed with 3 parts of sulphuric acid: on cooling, the chromic acid is deposited in crystals, The mother liquor being then decanted. Perhaps the method of producing chromic acid more generally followed commercially is to decompose chromium sulphate with lime and to heat to redness the resultant paste of lime, gypsum, and chromium oxide. The chromate of lime formed is treated with sodium sulphate to yield soluble sodium chromate and gypsum. The addition of sulphuric acid liberates the chromic acid. A less wasteful process than this is the electrolytic one now being worked in Germany by Lucius & Bruning. In a solution of chromium sulphate in sulphuric acid are immersed both lead anode and lead cathode, chromic acid being liberated on the former and hydrogen on the latter. A current at 3'5 volts with a current density of 300amperes per square metre is required, the cells being at the temperature of 50° C. (122o F.).

The wiki article on chromic acid says I should be able to obtain my acid by reaction of a dichromate with sulfuric acid. I see no mention of that in the previous methods.

From the wiki on chromic acid

The term chromic acid is usually used for a mixture made by adding concentrated sulfuric acid to a dichromate, which may contain a variety of compounds, including solid chromium trioxide. This kind of chromic acid may be used as a cleaning mixture for glass. Chromic acid may also refer to the molecular species, H2CrO4 of which the trioxide is the anhydride. Chromic acid features chromium in an oxidation state of +6 (or VI). It is a strong and corrosive oxidising agent.

I wish I had more refs to post and all that to prove that I've been searching and reading, but none of them give me the most basic answer, how do I make it, even theoretically. It's very frustrating because I have this idea that is all my own at this point but the hard part is hunting down the refs to put together the pieces I need to actually do the reaction. I have no problem spending a month or more doing something like this especially when it's my own idea. That does a lot for a newbie's confidence level. But, it gets tiresome searching day after day and the refs are just not there, yet I know they have to be somewhere, chromic acid was once upon a time a very common cleaning agent. The chemicals I have for this sythesis weren't exactly cheap, so I don't fancy blind experimentation, although I feel myself moving closer to that.

I know some of you feel telling me anything is spoon feeding me. This simply isn't true. Once I get this acid I have other things to find/synthesize before I can even test my idea which may not even work. I'm busting my ass here trying to not ask for hand outs, but I'm stuck. What would even be preferable to an answer is pointing me in the direction of an information source that I could lean on when I do have questions like this.

Any help is greatly appreciated and I am willing to conform to any standard of behavior necessary to get help from you guys. I have a ton of respect for some of you and to be taught by you is an honor and one that I very much appreciate.

this must be from an old article because the language is pretty out there.  bichromate of potassia = potassium dichromate.  Usually they refer to parts as by weight.*  This is a pretty useful oxidizing agent and not particularly dangerous considering its made and used in orgo1 labs in universities around the US.  As with any other reagent, take the necessary precautions with handling and don't be dumb. 

edit: *my mistake, "by measure" means by volume.  I'd prepare the the cold saturated solution by preparing a saturated RT solution, then chilling and scratching the flask to precipitate out the excess, then decant the liquid for measurement.

If you can tell us what you're using it for, maybe we can help figure out the best way to circumvent the use of chromic acid.  Be aware that it is a very strong acid and corrosive to boot.  If you have a fume hood, use it.  Anything you drop this on will corrode.  If you get it on your gloves, change them immediately.

Yes, im not a fan of Hexavalance Chromium compounds, perhaps its due to working in the welding industry for so long and that every new site makes us watch safety videos including the dangers of Chromium but I avoid it at all cost.

Something about volatile toxic compounds rubs me the wrong way. Especially when I won't know if I have been exposed until years later sometimes. Just working with it would foul my nerves up with worry so bad it just wouldn't be worth it to me.

Okay, specific question already. I know I will know my answer after I read more but I would like to not waste time by thinking something is one way when I got it all wrong. What confused me from the start about using a dichromate and dilute sulfuric acid to oxidize aldehydes and ketones was I couldn't find any clue as to how much of these things I was using. I finally think I get it and just wanted to hear someone say I did get it or I'm off.

Someone else did throw me a bone yesterday and told me that the oxidizer power of potassium dichromate is K2Cr2O7 --> K2O + Cr2O3 + 3 O:  and that means that every mole of  K2Cr2O7 can oxidize 3 moles of whatever. That may not be the right way to say it, but bear with me please. So that gives me my amount for the K2Cr2O7, it would be 1:3 K2Cr2O7/ketone or aldehyde. Next problem is the acid, how much to use there. I could find no reference to a target Ph or any kind of amount really. Just now I was reading one of the pdfs I found and saw the H3O was listed as a hydrogen source and R source. Funny as it sounds I didn't know what H3O was, so I google that. Knowing what that is now my thinking tells me that H2SO4 can break down into two H3O for every molecule (even though apparently it doesn't) I should be able to go 1:2 water/H2SO4. What I'm reading though says the second dissociation of H3O is not complete usually. So I would have to use an excess of acid. Can I use too much? I dunno, something about that last part I just aint feelin' it. I think I got something mixed up somewhere.
