Welcome but be careful with the citations
Thanks for your recent edits. Here are some suggestions to help you going forward. If you have questions, many editors can offer advice. Happy editing. --Smokefoot (talk) 13:53, 30 August 2014 (UTC)
 * Wikipedia prefers citations to reviews and books, not primary journal references (tens of thousands appear annually). For example in the years 2012 and 2013, acetaldehyde is discussed in more than 4080 papers, reports, and patents according to Chemical Abstracts Service.  We cant cite them all. For this reason, Wikipedia prefers secondary sources (reviews and books), we call this guideline WP:SECONDARY.
 * Many new editors are tempted to cite themselves or their colleagues. That behavior is inappropriate, it's called conflict of interest.
