Amine C-8

Gas chromatographic analysis of Amine C-8 shows the major components to be:

• Aminoethoxyethylmorpholine

• Hydroxyethoxyethylmorpholine

• 3-morpholinone

• Dimorpholinodiethyl ether

These constituents represent approximately two-thirds of the Amine C-8. Of the remainder, some of the components have been identified and some have not. Those which have been identified as present in small quantities are

• bis-(2-aminoethyl) ether
• 4-(2-aminoethyl) morpholine
• 2-(2-aminoethoxy) ethanol
• dimorpholinoethane
• diethylene glycol.

Intermediate in the preparation of corrosion inhibitors, emulsifiers, emulsion breakers, surfactants, thickening agents, and cement additives.

Amine C-8 is currently available in bulk and in drum of 470 pounds (213 kilograms) net weight.

Carbon steel is a satisfactory material for storing and handling Amine C-8. Copper, zinc, lead, or alloys containing any of these materials should not be used since they will be attacked by the amine.
The freezing point will vary over a wide range. Since it can freeze as high as 50°C (122°F), it will be necessary to provide heat to the storage tank. Generally, this can be done by utilizing either internal or external heating coils of a suitable area to heat the

tank contents. If these coils are internal, they should be built into the tank about six inches above the floor and operated on low- pressure steam. The coils should be constructed in such a manner as to allow the condensate to drain. Mild steel is acceptable for transfer lines. Since the product will leach conventional pipe dopes from threaded connections, the lines should be welded or flanged. Satisfactory gasketing materials are Garlock 7021, U.S. Rubber 899, John Crane 333, Johns- Manville 70, or equivalent. Carbon steel centrifugal pumps are satisfactory. Either pump packing or a mechanical seal may be used. Braided Teflon or asbestos are satisfactory packing materials. Seals may be John Crane Type 9, Durametallic Type RO-TT, or equivalent with either stellite and carbon or tungsten faces and Teflon V-rings.
