反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2,4-hexadiyn-1,6-diol bis(n-butylurethane) plus 2,4-hexdiyn-1,6-diol bis(ethylurethane)

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2,4-hexadiyn-1,6-diol bis(n-butylurethane) plus 2,4-hexdiyn-1,6-diol bis(ethylurethane)

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The limitation in this process is that the total number of diols and isocyanates or diols and organic sulfonic acid agents is at least three, thereby resulting in a co-crystallized composition directly recoverable from the reaction mixture. For example, methylisocyanate can be reacted with a mixture of 2,4-hexadiyn-1,6-diol and 3,5-octadiyne-1,8-diol to yield a co-crystallized composition of (1) 2,4-hexadiyn-1,6-diol bis(methylurethane) and (2) 3,5-octadiyn-1,8-diol bis(methylurethane). Similarly, methylisocyanate and ethylisocyanate can be reacted with 2,4-hexadiyn-1,6-diol to yield a co-crystallized composition of (1) 2,4-hexadiyn-1,6-diol bis(methylurethane), (2) 2,4-hexadiyn-1,6-diol bis(ethylurethane) and (3) 2,4-hexadiyn-1-ol-methylurethane-6-ol-ethylurethane. resulting in a co-crystallized composition directly recoverable from the reaction mixture
