Via Chemistry World (article by Maria Burke):
A 29-year-old man living in Knutsford, Cheshire, has been found guilty of possessing hydrochloric and sulfuric acids without a licence. The case raises questions about the responsibilities of wholesalers selling regulated chemicals to members of the public.
Concentrated hydrochloric and sulfuric acids are regulated because they can be used in the illicit manufacture of explosives or to cause harm. In November 2018, it became a criminal offence in the UK to possess sulfuric acid above a concentration of 15% without a licence. The law was tightened to combat rising acid attacks across the country. In October last year, hydrochloric acid above 10% w/w was among several chemicals added to the list of regulated substances. Others include hexamine, phosphoric acid (above 30% w/w) and zinc phosphide.
In a raid last November, police found a ‘makeshift chemistry lab’ in the bedroom of Ashlea Henderson. According to police reports, this consisted of 21 unknown chemicals, both in and out of their containers, along with a range of equipment. As a precautionary measure the police evacuated over 100 households and called in the bomb squad. It was seven hours before residents could return to their homes.
It is interesting to me that the phenomenon of home chemists exists outside the United States (this is the first report I've seen in 10+ years.) Nevertheless, I had not idea such legal strictures existed in the UK.
It seems to me that some enterprising small laboratory could make a bit of money by renting out a bit of space to local men who were interested in doing home chemistry, but I suspect that the legal risk would outweigh any revenue.
