Title: Improvements in cracking hydrocarbon oils
IPC: C10G9/00
Filed: 1929-06-29
Abstract: 337,380. Triggs, W. W., (Panhandle Refining Co.). June 29, 1929. Hydrocarbons, cracking.-In a process for ,cracking oils under reduced pressure, the oils are heated in a primary heating zone under suitable pressure at or above atmospheric and are then admitted to a flashing zone maintained under sub-atmospheric pressure, and the resulting vapours are passed to a cracking zone also under sub-atmospheric pressure. The crude oil is initially forced by a pump 54 through a preheating coil 57 into a flash pot 1 maintained at about 12-14 lbs. absolute pressure where the oil is vapourized and the vapours are passed through a cracking coil 56 at 1000-1200‹ and about 6-14 Ibs. pressure. The cracked vapours pass through a separating tower 6 and bubble towers 7, 8 where their temperature is controlled bv contact with cooling coils 26, 26<1>, 26<11>, 26<111>, 27, 28 through which the condensate from the towers 7, 8 is forced by pumps 13, 15 respectimely. Condensate from the tower 7 can also be injected into the tower 6 through a valve 18. The vapours from the tower 8 pass through a condenser 9 to a separator 10 from which condensate is withdrawn through a valve 29. The vacuum in the various parts of the system is determined by a pump 14 which withdraws vapours from the cracking zone through a line 40 and pumps them to the tower 6 through a line 39 or withdraws gases and uncondensed vapours 'from the separator 10 through a line 30 and pumps them through a line 42 to an absorption tower 11 supplied with washing liquid in the form of condensate withdrawn from the bottom of the tower 8. The condensate collecting at the bottom of the tower 11 is pumped by a pump 16 through a heat exchanger 17 and valve 33 into the middle of the tower 8. Burners 61 are provided in the upper portion of the furnace 2 as well as burners 62 in the lower zone, the burners' 61 being turned down after the plant is on flow, the coil 57 then being heated by waste gases of combustion passing through the perforations 63. In another construction the coils 56, 57 are arranged side by side and are separated by a wall. The burners 62 may be placed in arched side extensions of the zone 2 to avoid overheating the coil 56.

Patent GB-741017-A (GB)
Title: A process for hydroxylating olefinically unsaturated alcohols and aldehydes
IPC: C07C47/19
Filed: 1953-07-23
Abstract: Olefinically unsaturated alcohols and aldehydes are hydroxylated by adding a peroxide to a mixture comprising the alcohol or aldehyde and osmium oxide, the peroxide being added at such a rate that a detectable amount of black precipitate is present in the reaction mixture throughout the course of the reaction.  The preferred temperature of operation is in the range 20 DEG -50 DEG  C. Preferably a diluent, e.g. water or an organic solvent is used. Hydrogen peroxide is the preferred peroxide but other inorganic and organic peroxides may be used.  In the examples, (a) allyl alcohol is treated with hydrogen peroxide in the presence of osmium tetroxide to give glycerin; (b) acrolein is treated with hydrogen peroxide in the presence of osmium tetroxide to give glyceraldehyde; methacrolein and crotonaldehyde are similarly treated to give a - and lambda-methyl glyceraldehyde, respectively; (c) acrolein is hydroxylated as in (b) and the mixture is hydrogenated to give glycerin; (d) citral is hydroxylated according to the process of the invention and hydrogenated to give 3,7-dimethyl-1,2,3,7,8-pentahydroxyoctane; cinnamic aldehyde is treated similarly to give a -phenyl glycerin. Similarly olefinic aldehydes in which the double-bond is further removed from the aldehyde group may be hydroxylated by the process of the invention.  For example, 3,4-dihydroxypropanol is obtained from vinylacetaldehyde and 9,10-dihydroxyoctadecanal is obtained from oleic aldehyde.  Substituted olefinic aldehydes may also be used as starting materials, e.g. p - methoxyphenyl glyceraldehyde is obtained from p-methoxy cinnamic aldehyde, o-hydroxyphenyl glyceraldehyde is produced from o-hydroxy cinnamic aldehyde, and g -chloromethyl glyceraldehyde is produced from g -chlorocrotonaldehyde. Specification 540,534, [Group III], is referred to.
