Both industrially and in the laboratory, propionaldehyde has primary application as a chemical building block. [2]: 4 [4] It is predominantly used as a precursor to trimethylolethane (CH 3 C(CH 2 OH) 3) through a condensation reaction with formaldehyde. This triol is an important intermediate in the production of alkyd resins.
SuperLotto Plus is a lotto game played in the style of Mega Millions and Powerball. SuperLotto Plus is drawn every Wednesday and Saturday. The game began in 1986 as Lotto 6/49 (which was played similarly to the Canadian version of the game), then changed to SuperLotto somewhere in the 90s (with the matrix of 6/51).
The most common application of Grignard reagents is the alkylation of aldehydes and ketones, i.e. the Grignard reaction: [16] Reaction of CH 3 C(=O)CH(OCH 3 ) 2 with H 2 C=CHMgBr Note that the acetal functional group (a protected carbonyl) does not react.
In organic chemistry, methenium (also called methylium, carbenium, [2] methyl cation, or protonated methylene) is a cation with the formula CH + 3. It can be viewed as a methylene radical (: CH 2) with an added proton (H +), or as a methyl radical (• CH 3) with one electron removed.
tert-Butyllithium is a chemical compound with the formula (CH 3) 3 CLi. As an organolithium compound, it has applications in organic synthesis since it is a strong base, capable of deprotonating many carbon molecules, including benzene.
After no ticket was sold for Tuesday's jackpot, the top prize has been pushed to $1.28 billion for Friday's drawing, making it the second-largest jackpot in the game's history.
Powerball ticket. After a nearly three-month stretch with no one matching all six numbers, we finally have a winner of the record-setting $1.73 billion Powerball jackpot.
CH 2 =C(CH 3)CN + H 2 SO 4 + H 2 O → CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 + CH 3 OH → CH 2 =C(CH 3)COOCH 3 + NH 4 HSO 4. Mitsubishi Gas Chemicals proposed that MAN can be hydrated to methacrylamide without using sulfuric acid and is then esterified to obtain MMA by methylformate. [10] CH 2 =C(CH 3)CN + H 2 O ...
