Triglyceride 3 NaOH / H 2 O Δ 3 × soap 3 × glycerol Triglycerides can be saponified with sodium hydroxide to give glycerol and fatty sodium salt or soap. Typical plant sources include soybeans or palm. Animal-derived tallow is another source. From 2000 to 2004, approximately 950,000 tons per year were produced in the United States and Europe; 350,000 tons of glycerol were produced in the U ...
Propanethiol's basic molecular formula is C 3 H 7 SH, and its structural formula is similar to that of the alcohol n-propanol. Propanethiol is manufactured commercially by the reaction of propene with hydrogen sulfide with ultraviolet light initiation in an anti- Markovnikov addition. [ 8 ]
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.

For example, the three isomers of xylene CH 3 C 6 H 4 CH 3, commonly the ortho-, meta-, and para-forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene. The cyclic structures can also be treated as functional groups themselves, in which case they take the prefix "cyclo alkyl -" (e.g. "cyclohexyl-") or for benzene, "phenyl-".
1,3-Propanediol is mainly produced by the hydration of acrolein. An alternative route involves the hydroformylation of ethylene oxide to form 3-hydroxypropionaldehyde. The aldehyde is subsequently hydrogenated to give 1,3-propanediol. Biotechnological routes are also known. [2] Two other routes involve bioprocessing by certain micro-organisms:
For concentrations of hydrogen sulfide less than 2 mg/L aeration is an ideal treatment process. Oxygen is added to water and a reaction between oxygen and hydrogen sulfide react to produce odorless sulfate. [54] Nitrate addition Calcium nitrate can be used to prevent hydrogen sulfide formation in wastewater streams.
