Too busy to write!
Hi Friends,
I am getting quite busy with my schedule, which is the reason I am not getting time to write my experiments. I will try to write them as soon as possible. Don’t worry I have them jotted down in my notes, but just not on the mahine. I will hopefully [...]
Convinient Methylation process…
Found a convinient methylation process. Going to try out that agaisnt the one with methly iodide… Here is the process…
Gallacetophenone 3,4-dimethyl ether
To a boiling mixture of gallacetophenone (16.8g, 1 mol), benzene (400 mL) and anhydrous K2CO3 (55g) was added methyl sulphate (26.5g, 2.05 mol) in one portion, and the whole refluxed for 6 h with [...]
Methylation Reaction – A small test!
Today was a good day! I learned a lot from the research reactions that I have been carrying out. Its really a great learning exprience. Okay, today what I did was methylation of my product that I have synthesized earlier. I have described the product synthesis here. Let me call the reactant “A”. Okay, here [...]

Research Introduction
What I am going to do from now on, is probably write down every thing I research. I will try to be as regular as I can be in the course of my writing. Let me begin with writing about the reaction that I carried out the other day. See you soon!
