TITLE(s): CHEMICAL COMPOUNDER (chemical)
Controls equipment that processes coal tar hydrocarbons into intermediate compounds for use in
manufacture of dyestuffs and pharmaceutical products: Measures coal tar derivatives, using balance
scales and volume indicators. Shovels or pumps derivatives into specified containers. Observes
recording instruments, and adjusts steam, water, and vacuum valves to regulate temperature and
pressure during chemical reactions that produce specified intermediates. Tests acidity of
intermediates, using pH indicators. Tests solubility of intermediates in liquids, such as water,
alcohol, and chloroform. Adds specified chemicals to intermediates to ensure that they meet
requirements. Dumps ice into intermediates to reduce temperature. Pumps intermediates through filter
to remove liquid residue. Heats intermediates and circulates vapors through condenser lines to
isolate components of intermediates. May be designated according to equipment tended as Kettle
Operator (chemical) II; Tub Operator (chemical); process involved as Bromination Equipment Operator
(chemical); Sulfonation Equipment Operator (chemical); or material produced as Optical-Brightener
Maker (chemical).
