Terpene Phenolic Resin (Polymerization Reaction).
Turpentine Oil/ + Phenol + BF3 Catalyst +Toluene Pinene (on 100% basis) 1455 + 430 + 900
→ Terpene Phenolic Resin + Toluene + Losses (e.g. 1800 + 860 → + Toluene-40 BF3-Full Qty. Inputs 1925 + BF3
TEREPENE PHENOLIC RESIN--- yield 1800 (95.5% on Pinene + Phenol).
Procedure for processing of Terpene phenolic resin
Precaution-
Kettle should be thoroughly cleaned and free from all foreign bodies and gel particles of earlier batches .Also the vertical and horizontal condenser must be cleaned thoroughly.
Procedure.
1-- Charge phenol and toluene in a reactor
2-- Heat to 120—125 ° C and maintain for 1-2 hr for remove complete water
3-- Cool to 50° C , add catalyst with in 30 min.
4-- Cool to room temp than stat addition of turpentine oil slowly within 5—6 hr and maintain the temp to
