- carey> Question 1: In very laymens terms please define: "Phthalic
- carey> ester solvent"
-
- These are esters of phthalic acid, which I think are benzene
- rings with two carboxylic acids attached to the ring. They are often
- ortho, but need not be so. Your question seems indeterminate; there
- are many "phthalic esters" Diethyl phthalate, dioctyl phthalate,
- etc, depending on the other part that attaches to the carbonyl.
-
- carey> Question In very laymens terms please define: "Phenyl Oxolate
- carey> ester"
-
- If you mean "phenyl oxalate ester" this is the phenyl ester
- of oxalic acid, which should be:
-
- ho-co-co-oh with o-phenyl instead of oh
-
- carey> Question 3: Can these be purchased in stable liquid forms, or
- carey> must they be synthisized in the lab? Are they toxic, or
- carey> hazerdous?
-
- Phthalates are stable and readily available, used as
- plasticisers in the polymer industry.
