Sulfur-free acidulation of tall oil soap |
| abstract |
Tall oil soap is subjected to a sulfur-free acidulation by contacting the soap with boron trifluoride or a complex thereof, which effectively converts the soap into tall-oil without the necessity of a conventional acidification. The contacting can be carried out in any convenient fashion with an amount of boron trifluoride or complex, preferably in a range of about 20-24% based on the weight of the crude tall-oil soap. |
