Glove continuous process

Heavier weight gloves may be made by the continuous process in a similar manner to that described above, but they are more commonly produced by the batch process, outlined as follows. 

Li reacts readily with N2 to form Li3N. We have had an indication that other Li-N compounds of different stoichiometry can also be formed [15,18], However, these reactions only take place in an 02-free atmosphere. Hence, in a usual glove box atmosphere from which 02 is continuously removed, while N2 may exist in a concentration of hundreds of ppm, freshly prepared Li surfaces may always be covered by Li3N film. This film has a typical absorption in the IR, appearing as a broad peak around 680 cm1 [18]. Li3N is a strong base and nucleophile which can further react with alkyl carbonate and ester solvents [18]. In solutions, the reaction between Li and N2 is much less important, due to competition with other reduction processes (of solution species). 

There are a number of variations on the dipping technology (86), such as the type of manufacturing process (e.g., batch for thicker gloves or continuous...
