2-dodecylphenol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a 2 liter 4-necked reaction flask equipped with a stirrer, Dean Stark trap, condenser and nitrogen sparger were charged dodecylphenol (524 g, 2.0 m), trioxane (60 g, 0.66 m) and tetraethylene pentamine (TEPA) (189 g, 1.0 m). The temperature was raised slowly to 110° C. at which time water evolution began. After 8 hours the temperature had risen to 115° C. and water evolution ceased (42 cc's of water were collected). The mixture was cooled and filtered to yield 730g of a dodecylphenol-TEPA product containing 9.1% nitrogen. To a 2 liter 4-necked reaction flask equipped with a stirrer were collected) The mixture was cooled filtered

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of dodecyl phenol (1.0m., 262g.), sulphur (1.0m., 32g.) and caustic soda (8g.) was heated, with stirring, under nitrogen, at 160° C until the evolution of hydrogen sulphide ceased (42 hrs.). The caustic soda was neutralized with 10 ml. of phosphoric acid (SG = 1.75) and the mixture was then filtered. %S of Product = 5.85 (calc. = 5.8). was heated (42 hrs.) of phosphoric acid (SG = 1.75) and the mixture was then filtered

Procedure: First, dodecyl phenol was prepared. Specifically, to a 2-liter four-necked flask, 325 g of phenol and 30 g of dried activated clay (manufactured by MIZUSAWA INDUSTRIAL CHEMICALS, LTD.: product name, Galeonite #136) were added. 575 g of 1-dodecene was dropped in this mixture with agitation at 135 degrees C. for 4 hours. The activated clay was filtered, and then 537 g of dodecyl phenol was obtained by vacuum distillation. First, dodecyl phenol was prepared The activated clay was filtered
