hi
I want to synthesis the compound,but I don't find the line of compound,i want from dichloroacetia acid and urea to the compound,you see if the line is
impossible?

"The line of the compound," isn't an English argument and "dichloroacetia" isn't correct usage either. Did you mean, dichloroacetic acid?
Please try using your own language and then get someone who is bi-lingual to translate it for you. Also, utse, please.
This is what I've inferred from your post: you want to make allontoic acid and you think you can make it from urea and dichloroacetic acid and you're
asking if others, here, believe that to be a feasible approach.
I would not attempt a synthesis without first reading everything I could about it most particularly whether anyone has gone the route you propose.
Two more comments, the closely related allontoin is common throughout the cosmetics/health business. I did a quick search at the ACS website and
found 63 articles. I added the term 'synthesis' and reduced the number to 42.
UTSE and look for references. Then if you need help getting papers come back and ask.

thanks for your help
sorry, a mistake, is diacetic acid.
I say chinese, because I want to practice to speak english.
can you give me some advice or somearticles?

What is "diacetic acid"?
Why don't you first search the literature and patents and then ask others if they have an alternative idea? It is considered impolite to ask for an
advice without showing any effort yourself.
Anyway, from a glance at its structure I would say it is prepared from glyoxylic acid (HOOC-CHO) and urea. It might not be that simple though.

diacetic acid = acetic anhydride?
octave - 17-2-2008 at 09:55
or is it Acetoacetic acid
godson - 18-2-2008 at 01:07
sorry,is dichloroacetic acid

And Cl2CH-CO2H is apparented to (HO)2CH-CO2H --> O=CH-CO2H + H2O

A quick literature search revealed that allantoic acid is prepared by partial hydrolysis of allantoin (several references) or from glyoxylic acid
(only one reference). Seems like there is not much interest in its preparation or use as reagent. It mostly only has biochemical relevance.

who can provide the reference or better line,etc partial hydrolysis of allantoin (several references) or from glyoxylic acid (only one reference).
thanks

Obvious;y you have internet access. The best person to search the online literature and references, which are massive, is you, yourself.
Obtain and use Merck Index. You can get it for free.
As nicodem said, this is simply not a compound that many of us are interested in.
