Production process and use for propargyl alcohol and its intermediate

Abstract

Processes are provided for producing propargyl alcohol in an industrially advantageous manner. One of the processes comprises reaction of 1,2,3-trichloropropane with 3 equivalents or more of an alkali compound to produce propargyl alcohol. The other process comprises (1) a first step of reaction of 2,3-dichloro-1-propanol with an amine to produce chloroallyl alcohol, and (2) a second step of reaction of the chloroallyl alcohol obtained in the above step (1) with an alkali compound to produce propargyl alcohol.

What is claimed is:  
     
         1 . A propargyl alcohol reduced in formaldchyde, wherein the formaldehyde content is 1,000 ppm or less.  
     
     
         2 . The propargyl alcohol as claimed in  claim 1 , wherein the formaldehyde content is 100 ppm or less.  
     
     
         3 . The propargyl alcohol as claimed in  claim 1 , wherein the formaldehyde content is 5 ppm or less.  
     
     
         4 . The propargyl alcohol as claimed in  claim 1 , further containing a polymerization inhibitor.  
     
     
         5 . The propargyl alcohol as claimed in  claim 4 , wherein the polymerization inhibitor is at least one compound selected from the group consisting of phenol compounds, vinyl compounds, sulfur-containing compounds, nitrogen-containing compounds, and metal compounds.  
     
     
         6 . A resin, which is obtained by reaction of the propargyl alcohol according to any one of  claims 1  to  5 .  
     
     
         7 . A resin composition, comprising the resin according to  claim 6 .  
     
     
         8 . A cationic electrodeposition coating composition containing the resin composition according to  claim 7 .  
     
     
         9 . The propargyl alcohol as claimed in any one of  claims 1  to  3 , which is obtained by a process comprising reacting 1,2,3-trichloropropane with 3 equivalents or more of an alkali compound in the presence of a quaternary ammonium salt and/or a polymerization inhibitor, wherein said reaction comprises a first step of reacting 1,2,3-trichloropropane with an alkali compound to produce 2-chloroallyl alcohol and a second step of reacting said 2-chloroallyl alcohol with an alkali compound to produce propargyl alcohol.  
     
     
         10 . The propargyl alcohol as claimed in any one of  claims 1  to  3 , which is obtained by a process comprising reacting 1,2,3-trichloropropane with an aqueous solution containing 3 equivalents or more of an alkali compound in the presence of a quaternary ammonium salt and/or a polymerization inhibitor, wherein said reaction comprises a first step of reacting 1,2,3-trichloropropane with an aqueous solution containing an alkali compound to produce 2-chloroallyl alcohol and a second step of reacting said 2-chloroallyl alcohol with an aqueous solution containing an alkali compound to produce propargyl alcohol.  
     
     
         11 . The propargyl alcohol as claimed in any one of  claims 1  to  3 , which is obtained by a process comprising the following two steps: 
 (1) a step of reacting 2,3-dichloro-1-propanol with an amine to produce chloroallyl alcohol, and  
 (2) a step of reacting the chloroallyl alcohol obtained in said step (1) with an alkali compound to produce propargyl alcohol.
