十二烷基琥珀酸

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a 4-necked flask 1 mole of dodecenylsuccinic anhydride and 1 mole of allylalcohol were reacted together at 110°±5 ° C. for 2 hours to form a monoallyl ester of dodecylsuccinic acid. The product thus obtained was then converted to its triethanolamine salt whihc is a viscous yellowish brown liquid having a good self-emulsifiability in water.

实验步骤: The reaction was carried out in substantially the same manner as in Example 7, by using 27.2 g (0.075 mol) of the dipotassium salt of dodecylsuccinic acid as the initial materials (the salt was prepared in the manner described in Example 5), 33.3 g (0.075 mol) of tetraphosphorus decasulfide, and 9.3 g (0.3 mol) of red phosphorus, as well as 100 ml of dichlorobenzene as a solvent. The yield of dodecylthiophene was 48% (b.p. 196° C./20 mbar). was prepared in the manner
