WebThe potential for cross sensitization between the industrial allergen 2-amino-4-chloro-phenol (ACP) and PAP was studied in guinea pigs (strain not indicated). Fifteen guinea pigs were injected intracutaneously with ACP and then challenged with ACP and PAP. No reaction to PAP was elicited by challenge with 1.0% PAP for up to six weeks. Ref.: A1 WebAbstract. This paper is a thorough investigation of the chemical transformations during pyrolytic conversion of phenolic resins to carbons, and reports that all carbons obtained from main-stream phenolic resins including phloroglucinol–formaldehyde (FPOL), phloroglucinol–terephthalaldehyde (TPOL), resorcinol–formaldehyde (RF), and …
