2-ethoxyethyl 2-cyanoacetate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-Butyloxyethyl 2-cyanoacrylate was prepared in the same manner as in Example 1, except that butyloxyethyl 2-cyanoacetate was substituted for the 2-ethoxyethyl cyanoacetate. The 2-cyanoacrylate obtained contained 400 ppm. of moisture, 0.05% of 2-butyloxyethyanol and 0.3% of 2-butyloxyethyl cyanoacetate. To the above 2-cyanoacrylate was added 20 ppm. of SO2. Adhesive compositions were prepared by adding an antioxidant as shown in Table 2 to the 2-cyanoacrylate.
