Record number: 1, Textual support number: 1 DEF
An equimolar mechanical mixture of crystals each one of which contains only one of the two enantiomers present in a racemate. 1, record 1, English, - racemic%20conglomerate
Record number: 1, Textual support number: 1 OBS
The process of its formation on crystallization of a racemate is called spontaneous resolution, since pure or nearly pure enantiomers can often be obtained from the conglomerate by sorting. 1, record 1, English, - racemic%20conglomerate
Record number: 1, Textual support number: 2 OBS
racemic mixture: The term is confusing since it has been used as a synonym for both "racemate" and "racemic conglomerate." Usage strongly discouraged. 1, record 1, English, - racemic%20conglomerate

Mélange équimoléculaire mécanique de cristaux dont chacun ne contient qu'un seul des deux énantiomères présents dans le racémate. 4, record 1, French, - conglom%C3%A9rat%20rac%C3%A9mique
Record number: 1, Textual support number: 1 OBS
Le processus de sa formation par cristallisation d'un racémate est nommé dédoublement spontané car des énantiomères purs, ou sensiblement purs, peuvent souvent être obtenus par tri à partir du conglomérat. 4, record 1, French, - conglom%C3%A9rat%20rac%C3%A9mique
Record number: 1, Textual support number: 2 OBS
mélange racémique : Cette expression prête à confusion car elle a été utilisée comme synonyme à la fois de «racémate» et de «conglomérat racémique». Usage fortement déconseillé. 4, record 1, French, - conglom%C3%A9rat%20rac%C3%A9mique

Un racemato o modificación racémica puede pertenecer a una de estas dos clases diferentes : o bien el sólido cristalino es un conglomerado, esto es una mezcla mecánica de cristales de dos enantiómeros puros, donde cada molécula enantiomérica está separada en su propio cristal enantiomérico, o bien el sólido cristalino es un compuesto racémico(este es el caso más generalizado) en que las dos moléculas enantioméricas están presentes en iguales cantidades pero ordenadas dentro de la estructura de un único cristal. 1, record 1, Spanish, - conglomerado

Record number: 2, Textual support number: 1 DEF
An equimolar mixture of a pair of enantiomers. 4, record 2, English, - racemate
Record number: 2, Textual support number: 1 OBS
It does not exhibit optical activity. The chemical name or formula of a racemate is distinguished from those of the enantiomers by the prefix (±)- or rac- [in italics] (or racem-) [in italics) or by the symbols RS and SR. 4, record 2, English, - racemate
Record number: 2, Textual support number: 2 OBS
The prefix dl- (dextro-, for dextrorotatory, and levo-, in full levorotatory) has also been used but should be avoided. The symbol "±" is nowadays to be preferred. 5, record 2, English, - racemate
