It has been our experience that the oil length of the alkyd must be around 40#. 5) Effectiveness of Driers In order to determine the effectiveness of metallic driers on oxidizing alkyds in oatalyzed urea formaldehyde finishes, the following driers were evaluated in various percentages In formulations containing short and medium oil alkyds> (9 0 3) Lead Naphthenate (9 0 53) Cobalt Naphthenate (9 0 43) Manganese Naphthenate (3 Q 4l) Calcium Octoate (9 G 61) iron Naphthenate 6# 6# 5# 6# The samples were poured on glass against a comparable formulation without driers and tested for hardness after baking for 1 hour at l4oP, , after over night air drying and after 24 hours air drying.

The dusts or fumes derived from the heavy metals like lead, mercury, and manganese can be highly toxic and poisoning from these substances has been recognized for many years.

CAUTION: If a valve of any type is installed in the piping leading to or from the expansion tank, BE SURE THAT IT IS ALWAYS?

This mass, which measures approximately 4 cm in its greatest or vertical diameter, and about 3 cm in width at its base, has a grey appearance, a friable center, no definite capsule, and has blood vessels and bronchi leading into its apex.

It is concluded that a detailed laboratory study of the autoclave reaction could lead to an appreciable diminution of TCDD formation, and such a study is in the planning `stage. 10/65 /8 11/66 Dow was contacted concerning removal of TCDD and its disposal, but any information obtained was not in the available documentation. 274,275 A number of projects for reduction of dust and fumes in the Nitro plant were undertaken.1^0 Al T O W O R K FaCOOCT Rev. 1 - 11/5/82 ATTORNEY-CLIENT PRIVILEGE VII BASIC CHEMISTRY OF 2,4.,5-T PRODUCTION - Page 28 B.
