Science - Chemistry; Chem Sci/Eng / resolution of modafinic acid by the AS3PC method | | French term or phrase: masse de la chaussette | This is a heading in a table of results from resolving modafinic acid in ethanol. Other column headings include such things as run, wet mass, dry mass, mass of retained liquor, spin speed and time, pure enantiomer, and stock solution. Can anyone help (quickly, please!) with this meaning of chaussette?
Thanks in advance. |

I know nothing whatsoever about this, so I'm giving it only medium confidence.
Tout spécialement, la présente invention concerne le dédoublement des sels de potassium de 1 Oméprazole racémique par cristallisation préférentielle et notamment par le procédé AS3PC (cristallisation préférentielle polythermique programmée et auto-ensemencée) [ ... ]
La filtration a lieu au moyen d'une essoreuse (RA20 Rousselet-Robatel) à 5000 tours/min munie d'une CHAUSSETTE DE 20 CM DE DIAMÈTRE, DE 10 CM DE HAUTEUR ET DONT LE DIAMÈTRE DES PORES DU MÉDIA FILTRANT EN NYLON EST DE 20 ΜM. La liqueur mère récupérée est transvasée dans le réacteur pour la cristallisation préférentielle suivante.

For liquid-liquid extraction, "socks" may be used:
or they may be dry-loaded by transferring them into an empty column through a chute or FABRIC SOCK (typical of metal or plastic packings). The familiar ring and saddle packings such as Raschig rings, Berl saddles, Intalox saddles, and Lessing rings are examples of ceramic packings. The more modern metal and plastic random packings such as Pall rings, Hy-Pak®, and IMTP® packings are ring or saddle shapes with internal fingers and slots in the wall. These packings are more open and provide greater access to the interior surfaces for improved capacity and masstransfer performance. Structured packings are modular assemblies placed inside the column in a specific arrangement. Many are in the form of woven wire mesh or crimped sheets arranged in layers at specific angles. For packing made from sheets, it is not clear whether surface treatments such as perforations and embossing are important in liquid-liquid extraction

Presumably the "nylon filtering media" referred to above is actually a "sock", but takes the name of the frame or basket in or over which it sides (reading between the lines).
