Pozdravljeni.
Naredil sem a-pvp sintezo iz kupljenega
2-bromovalerofenona. To je bila precej preprosta reakcija.
Sedaj sem izparil večino etil acetata, dodal aceton, dobil ph na 5 in ne morem dobiti kristalov. Poskušal sem raztegniti steklo, izpariti več topila, vendar še vedno nič.
Ima kdo izkušnje s tem vprašanjem?

Raztopino uparite, dokler se na površini ne pojavi film. nato pustite čez noč v zamrzovalniku (-18/-20C). vse bi moralo kristalizirati.
