Process for the preparation of a polysulfide |
| abstract |
Process for the preparation of polysulfide of formula (I) HS-(CH 2 ) n -O-(CH 2 ) m -O-(CH 2 ) p -[S-S-CH 2 ) n -O-(CH 2 ) m -O-(CH2) p ] q -SH (I) wherein m is an integer in the range 1 to 4, n and p are integers in the range 1-10, and q is an integer in the range 1-60, by oxidizing a bismercaptodiether compound of formula (II) HS-(CH 2 ) n -O-(CH 2 ) m -O-(CH 2 ) p -SH (II) with elemental sulfur in the presence of a base and a protic solvent. This process has a high selectivity towards linear disulfides. |
