WH Perkin, Patent AD 1856 No 1984: a review on authentic mauveine and related compounds

Posted on 12. March, 2018.

Prior to 1856, the year in which Perkin patented mauveine, dyestuffs were usually prepared from plant, animal or mineral sources. For example, the red dye alizarin came from the root of the madder plant, indigo came from the cotton plant and Tyrian purple came from certain shellfish. From 1856 many patents appear on dyes made by chemical synthesis, of which mauveine was the first to be commercialised. This mauveine patent marks the beginning of the coal-tar dye industry which spread rapidly through Britain, France, Germany and Switzerland. It has had numerous celebrations and reviews.

Free for 24 hours - The mechanism of the reaction of the Tollens reagent

Posted on 7. March, 2018.

The Tollens test for aldehydes has been used for over 100 years but no reason has been given for adding sodium hydroxide to the silver nitrate before the solution is cleared with ammonia. In this paper, a mechanism is proposed which explains why the addition of alkali makes the test much more sensitive.

2018: Year of the Bird
2018 marks the centennial of the Migratory Bird Treaty Act. To honour this milestone, National Geographic, the National Audubon Society, the Cornell Lab of Ornithology and BirdLife International are joining forces with more than 100 other organisations to celebrate 2018 as the Year of the Bird.
This effort aims to heighten public awareness of birds because of their wonder and beauty, and because they symbolise nature’s interconnectedness and the importance of caring for our shared planet.
To get started, visitors to BirdYourWorld.org will discover simple but meaningful steps that anyone can take to help birds each month and join a pledge to participate. These steps include participating in the worldwide Great Backyard Bird Count in February, putting in native plants in the spring, and cutting back on the use of plastic materials.

Through 12 months of storytelling, science research, and conservation efforts, Year of the Bird will examine how our changing environment is driving dramatic losses among bird species around the globe and highlight what we can do to help bring birds back.
Participating organisations include nonprofit and conservation groups, state and federal agencies, zoos, nature centres, and ornithological societies that are working together to raise the visibility of birds and inspire action through #BirdYourWorld throughout 2018. The campaign will also utilise National Geographic’s portfolio of media platforms reaching millions of people around the world with engaging bird content that will educate, inspire, and raise awareness about the challenges that birds are facing and what people can do to help.

Free from the Science Reviews archive: Zinc/ammonium formate: a new facile system for the rapid and selective reduction of oximes to amines

Posted on 1. March, 2018.

Abstract

Various oximes, both aldoximes and ketoximes, are selectively reduced to corresponding amines employing low cost zinc dust and ammonium formate despite presence of other functional groups such as halogens, –OH, –OCH3, –COOH, –CN, > C = C < and –CH3.
