    MSG production / synthesis

    Someone is telling me this, but I think I’m being played. Does the following ring true? Does it even make sense? Appreciate any thoughts on this. Thanks in advance. MSG is no longer synthesized from acrylonitrile. It’s either produced through bacterial fermentation or acid hydrolysis of...

    synthesis of ammonium magnesium phosphate x 6 H2O

    Any help appreciated, it's been 37 yrs. since I was in univ. chemistry class. Trying to flesh out the stochiometric/molar quantities (grams) of magnesium oxide to be combined with monoammoniumphosphate (MAP, a common fertilizer) to create ammonium magnesium phosphate x 6 H2O ? I'm guessing I...

    organic synthesis

    Hi, I'm doing some past exam questions and have got stuck on the attached question. Although I think I've got a solution to part I) (Witting reaction, followed by reaction with OSO4 and then and then reacting with a dibromide compound) I am very stuck on part b. For part b I have tried a...

    H2O2 from H2O & O3?

    ok, I read this is possible via a random comment somewhere on the internet, so I'm trying to do some research to see if it's true, but most of the sites I come across are these 'alternative health' sites that I don't really trust.. anyways, on with the question. I'm trying to: 6,H2O + 2,O3 ->...

    Phosphorus Oxychloride Synthesis question

    Can anyone give some advise on the POCI3 synthesis? Some seem very simple, like: 2 PCl3 + O2 → 2 POCl3 But what is the ( 2 ) ? and how is this actually done? A supply of Oxygen and an inert reaction flask with the Phosphorus trichloride? And : PCl5 + H2O → POCl3 + 2 HCl How do you isolate the...

    Troubles with organic synthesis of sulfo derivatives

    I know that D is methylbenzene. Also they say in the task, that sulfonation of d gives two isomers, and the reactions further are conducted upon the main isomer. I think it is para-sulfotoluene, because of steric reasons. Next simple chlorination, and oxidation of side chain alkyl group (methyl)...
