Method for the preparation of aliphatic chloroformates
-
Page/Page column 7-8, (2008/06/13)
A method for preparing an aliphatic chloroformate comprising, introducing a mixture of at least one aliphatic hydroxyl compound, phosgene, at least one solvent, and optionally at least one organic base into a flow reactor to obtain a unidirectional flowing reaction mixture. The at least one aliphatic hydroxyl compound comprises at least one aliphatic hydroxyl group. The unidirectional flowing reaction mixture is maintained at a temperature between about 0° C. and about 60° C. to produce a single product stream comprising an aliphatic chloroformate.

Aromatic-aliphatic diamines of the formula STR1 in which Ar is an arylene or substituted arylene are useful in preparing thermally stable, rigid, polyamides, polyureas and polyurethanes having a repeating unit of the formula STR2 in which Ar is arylene or substituted arylene, X is --NH-- or --O--, n is 0 or 1, and R is a divalent organic radical.
1-Aziridine carboxylic acid derivatives with immunostimulant activity
-
, (2008/06/13)
2-Substituted-1-aziridine-carboxylic acid esters exhibiting immuno-stimulant activity and of the formula STR1 wherein X is a carbamoyl or alkoxycarbonyl radical, and R1 is an aliphatic hydrocarbon radical optionally substituted by halogen, alkoxy, amino, carbamoyloxy, cycloalkyl, hydroxyl, an imido or heterocyclic radical, cycloalkyl; or aryl, aralkyl, aryloxyalkyl or arylthioalkyl wherein the aryl moiety is optionally substituted by halogen, alkyl, alkoxy, hydroxyl, amino, nitro, cyano, acyl, carbalkoxy, thioalkyl, alkylsulphonyl, phenyl or trifluoromethyl. Counterparts where X is --CN and R1 is as above, except for ethyl, are also new.
