Sebacoyl chloride (or sebacoyl dichloride) is a di-acyl chloride, with formula (CH2)8(COCl)2. A colorless oily liquid with a pungent odor, it is soluble in hydrocarbons and ethers. Sebacoyl chloride is corrosive; like all acyl chlorides, it hydrolyzes, evolving hydrogen chloride. It is less susceptible to hydrolysis though than shorter chain aliphatic acyl chlorides.{{cite journal|last1=Morgan|first1=Paul W.|last2=Kwolek|first2=Stephanie L.|title=The nylon rope trick: Demonstration of condensation polymerization|journal=Journal of Chemical Education|date=April 1959|volume=36|issue=4|pages=182|doi=10.1021/ed036p182|bibcode=1959JChEd..36..182M}}
Preparation
Sebacoyl chloride can be prepared by reacting sebacic acid with an excess of thionyl chloride. Residual thionyl chloride can be removed by distillation.{{cite journal|last1=Erdmann|first1=L.|last2=Uhrich|first2=K.E.|title=Synthesis and degradation characteristics of salicylic acid-derived poly(anhydride-esters)|journal=Biomaterials|date=October 2000|volume=21|issue=19|pages=1941–1946|doi=10.1016/S0142-9612(00)00073-9|pmid=10941915}}
Use
Sebacoyl chloride can be polymerized with hexamethylenediamine yielding nylon-6,10.{{Cite journal|last1=Enkelmann|first1=Volker|last2=Wegner|first2=Gerhard|date=1976-11-01|title=Mechanism of interfacial polycondensation and the direct synthesis of stable polyamide membranes|journal=Die Makromolekulare Chemie|language=en|volume=177|issue=11|pages=3177–3189|doi=10.1002/macp.1976.021771106|issn=0025-116X}}
