Dear list,
According to the information on contextgarden (section chemistry)
chemical reactions should be entered as follows:
\usemodule[chemic]
\startformula
\chemical{CaCO_3(s),+,HCl(g),->,CaCl(HCO_3)(s)}
\stopformula
That produces a formula with the comma's in it, so that's not good. I
A happy new year to everyone!
I’m trying to generate PDF/A compliant files and have a Problem with chemical
formulas in text.
The following does not work:
\setupinteraction
[title=TITLE,
subtitle=SUBTITLE,
author=AUTHOR,
keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}]
%% For PDF/A
\setupbackend
\startplacechemical
\startchemicalformula
...
\stopchemicalformula
\stopplacechemical

I am busy to edit an older article in which there are a couple of chemical
fromulas and reactions.
However, I am stuck because the following throws me an error when uncommenting
the line with “\chemical{2H^\oplus}{~waterstof (zuur)}” (something with $
inserted…)

Dear Sirs,
I'm trying to run some code from the ppchtex manual, however, the chemical
structures are not correctly drawn. See the example:

I found this problem en Minimals (last version) and on TexLive 2013.

Hello,
We have completely rewritten the chemical macros from ppchtex, taking
some liberty with some details of the syntax. I will look into your
examples to see what is going wrong.

Hi all,
I found what I suppose to be a bug with the \chemical command:
- when one use \chemical inside display math, the spacing is wrong around the
\chemical stuff. The font change inside \chemical also persists outside the
command.
- if one enclose the \chemical command into curly braces

We are currently in the process of a complete re-write of the chemical macros.
In fact, we are almost finished and Hans is including the new macros in the
beta (as fast as he can keep up with my changes...).
In your example, I see the spacing problem in display math but do not see the
font
on line 3 where the last parenthesis is smaller than expected.
Rather than display math (as was suggested with ppchTeX), we have now
introduced \startchemicalformula
\stopchemicalformula
in order to display a chemical formula.
Yes but in my cases I do want a mathematic display

Hello all,
Is there a way to use comma character or semicolon character inside the
chemical formula?
Comma character is used as a delimiter of individual items in the formula.
When is there command for example \lettertilde, is there something like
\lettercomma (\charcomma), \lettersemicolon
