:Talk:Heptane

I am seeking of the integrity of Heptane after it has been filtered thru a 25-Micron filter. Will the Heptane slowly lose its integrity over each filteration or not? Also is there a shelf life of Heptane, days, weeks, months?

Thanks,

Brian

I added descriptions of the isomers abbreviated from data found on another web page, to assist students who may be trying to understand the concept. Dhaluza 03:36, 14 December 2006 (UTC)

Dear all,

If I'm correct, the defenition of "neo" in chemistry, is "A C-atom surrounded by 4 other C-aromt".

Therefore "Heptane" has 3 different "neoheptane's"

1) 2,2-Dimethylpentane, (H₃C)₃–C–CH₂–CH₂–CH₃

2) 3,3-Dimethylpentane, H₃C–CH₂–C(CH₃)₂–CH₂–CH₃

3) 2,2,3-Trimethylbutane, CH₃–C(CH₃)₂–CH(CH₃)–CH₃

All these above molecules, contain a C-atom surrounded by 4 other C-atoms. Therefore "NeoHeptane" does not specify a single molecule structure, and does not exist.

Thats why i removed the name "neoheptane" after 2,2Dimethylpentane.

Best regards,

A search for "Bestine" leads to this page. However, "Bestine" is not a type of solvent, it is a brand name of the Union Rubber Company, which also makes rubber cement products under the brand "Best-Test". I cannot find articles on any of these, and there really should be at least one. Union Rubber makes most of the rubber cement products in the US -- possibly in the world -- to the extent that when they were changing owners in 2016, it became nearly impossible to get rubber cement in any store, for almost 2 years.

I suggest that a Wikipedia page is needed for "Union Rubber Company", and that "Best-Test" and "Bestine" should redirect to that page, rather than here. — Preceding unsigned comment added by 70.89.176.249 (talk) 20:16, 17 April 2019 (UTC)
