\section{Introduction}
|
|
|
|
Acetylsalicylic acid (ASA), \ch{C9H8O4}, is a synthetic organic derivative of salicylic acid
|
|
and is commonly known as aspirin.\\
|
|
\begin{figure}[ht]
|
|

|
|
\vspace{1em} % Adds space above the molecule

|
\chemfig{*6(-=-(-O-[:-30](=[:-90]O)-[:+30]CH_3)=([:60]-[:90](=[:150]O)-[:30]OH)-=)}
|
|
\vspace{1em} % Adds space below the molecule
|
|
\caption{Chemical structure of ASA}
|
|
\label{fig:asa-structure}
|
|
\end{figure}
|
|
|
|
Commercial aspirin is commonly synthesized from salicylic acid through Eq~\ref{eq:aspirin-syn},
|
|
and the two molecules differ by an ester group (\ch{-OCOCH3}).
|
|
\begin{equation}
|
|
\ce{C7H6O3 + C4H6O3 ->[H2SO4] C9H8O4 + CH3COOH}
|
|
\label{eq:aspirin-syn}
|
|
\end{equation} \\
|
|
Another common derivative product of salicylic acid is methyl salicylate, \ch{C8H8O3}, commonly referred to
|
|
as wintergreen oil. Methyl salicylate is commonly used in edibles (e.g. gum, mints), perfumes, and pain-relief
|
|
ointments (e.g. Icy Hot, BenGay). Methyl salicylate also differs with salicylic acid by a single ester group and
|
|
has simply been esterified differently than ASA. \\
|
|
|
|
\begin{figure}[ht]
|
|
\centering
|
|
\vspace{1em} % Adds space above the molecule
|
|
\chemfig{*6(-=-(-OH)=([:60]-[:90](=[:150]O)-[:30]O-[:+90]CH_3)-=)}
|
|
\vspace{1em} % Adds space below the molecule
|
|
\caption{Chemical structure of methyl salicylate}
|
|
\label{fig:methyl-salicylate}
|
|
\end{figure}
|
|
|
|
Due to the similarity between the two molecules, ASA can be reacted to synthesize methyl salicylate.
|
|
The purpose of this experiment was to convert acetylsalicylic acid obtained from
|
|
commercial aspirin tablets into methyl salicylate through acid-catalyzed esterification
|
|
in methanol under reflux conditions.
|
|
|
|
|
|
\section{Results and discussion}
|
|
|
|
\subsection{Outline}
|
|
|
|
The document layout should follow the style of the journal concerned. Where
|
|
appropriate, sections and subsections should be added in the normal way.
|
|
|
|
\subsection{References}
|
|
|
|
References should be given in the normal way in \LaTeX{}. If you are using
|
|
\textsf{biblatex} (as recommended) then you can use the full range of citation
|
|
commands it provides. If you choose to use classical Bib\TeX{}, the
|
|
\textsf{natbib} package will be loaded and you can use it's commands.
|
|
|
|
\subsection{Floats}
|
|
|
|
New float types are set up in the preamble. The means graphics are included as
|
|
follows (Scheme~\ref{sch:example}). As illustrated, the float is ``here'' if
|
|
possible.
|
|
\begin{scheme}
|
|
\centering
|
|
Your scheme graphic would go here: PDF graphics are recommended.
|
|
%\includegraphics{graphic}
|
|
\caption{An example scheme}
|
|
\label{sch:example}
|
|
\end{scheme}
|
|
|
|
|
|
|
|
The use of the different floating environments is not required, but it is
|
|
intended to make document preparation easier for authors. In general, you
|
|
should place your graphics where they make logical sense; the production
|
|
process will move them if needed.
|
|
|
|
\subsection{Math}
|
|
|
|
If packages such as \textsf{amsmath} are required, they should be loaded in the
|
|
preamble. However, the basic \LaTeX\ math(s) input should work correctly
|
|
without this. Some inline material $1 + 1 = 2$ followed by some display. \[ A =
|
|
\pi r^2 \]
|
|
|
|
It is possible to label equations in the usual way (Eq.~\ref{eqn:example}).
|
|
\begin{equation}
|
|
\frac{\mathrm{d}}{\mathrm{d}x} \, r^2 = 2r \label{eqn:example}
|
|
\end{equation}
|
|
This can also be used to have equations containing graphical content. To align
|
|
the equation number with the middle of the graphic, rather than the bottom, a
|
|
minipage may be used.
|
|
\begin{equation}
|
|
\begin{minipage}[c]{0.80\linewidth}
|
|
\centering
|
|
As illustrated here, the width of \\
|
|
the minipage needs to allow some \\
|
|
space for the number to fit in to.
|
|
%\includegraphics{graphic}
|
|
\end{minipage}
|
|
\label{eqn:graphic}
|
|
\end{equation}
|
|
|
|
\section{Experimental}
|
|
|
|
The usual experimental details should appear here. This could include a table,
|
|
which can be referenced as Table~\ref{tbl:example}. Notice that the caption is
|
|
positioned at the top of the table.
|
|
\begin{table}
|
|
\caption{An example table}
|
|
\label{tbl:example}
|
|
\centering
|
|
\begin{tabular}{ll}
|
|
\hline
|
|
Header one & Header two \\
|
|
\hline
|
|
Entry one & Entry two \\
|
|
Entry three & Entry four \\
|
|
Entry five & Entry five \\
|
|
Entry seven & Entry eight \\
|
|
\hline
|
|
\end{tabular}
|
|
\end{table}
|
|
|
|
Adding notes to tables can be complicated. Perhaps the easiest method is to
|
|
generate these using the basic \texttt{\textbackslash textsuperscript} and
|
|
\texttt{\textbackslash emph} macros, as illustrated (Table~\ref{tbl:notes}).
|
|
\begin{table}
|
|
\caption{A table with notes}
|
|
\label{tbl:notes}
|
|
\centering
|
|
\begin{tabular}{ll}
|
|
\hline
|
|
Header one & Header two \\
|
|
\hline
|
|
Entry one\textsuperscript{\emph{a}} & Entry two \\
|
|
Entry three\textsuperscript{\emph{b}} & Entry four \\
|
|
\hline
|
|
\end{tabular}
|
|
|
|
\textsuperscript{\emph{a}} Some text;
|
|
\textsuperscript{\emph{b}} Some more text.
|
|
\end{table}
|
|
|
|
The example file also loads the optional \textsf{chemformula} and
|
|
\textsf{mhchem} packages, so that formulas are easy to input:
|
|
\texttt{\textbackslash ce\{H2SO4\}} gives \ce{H2SO4}. The two have similar
|
|
syntax but authors may prefer one or the other.
|
|
|
|
The use of new commands should be limited to simple things which will not
|
|
interfere with the production process. For example, \texttt{\textbackslash
|
|
mycommand} has been defined in this example, to give italic, mono-spaced text:
|
|
\mycommand{some text}.

Some journals require a graphical entry for the Table of Contents. This
|
|
should be laid out ``print ready'' so that the sizing of the text is correct.
|
|
|
|
The space available depends on the journal: J. Am. Chem. Soc. allows 3.25 in
|
|
by 1.75 in and requires sanserif text. Some journals want different sizes:
|
|
you can easily adjust here.
|
|
|
|
The two rules either side of the content are there to help judge the height
|
|
of your material: they may be deleted once not required.
