Title: Polymerisation of Aryl Vinyl Hydrocarbons using a plurality of Catalysts
IPC: C08F2/16
Filed: 1967-03-04
Abstract: Arylvinyl hydrocarbons are polymerized in aq. suspension in the presence of at least 3 different free radical catalysts, the half-periods of which at 100 C. in benzene are respectively 3-30 min. for the first, 15-60 min. for the second and 100-2000 min. for the third, the polymerization being carried out in 3 successive stages with the operating temperatures for the 2nd and 3rd stages being higher than that for the preceding stage and the catalysts and temperatures being so chosen that the 2nd and 3rd catalysts do not commence to act until the temperatures of the 2nd and 3rd stages respectively have been reached, the relative proportions of the 1st and 2nd catalysts being so chosen that the rate of polymerization is the same before and after the 2nd catalyst has started to act. In examples styrene is polymerized in an aq. mixture of mineral oil (as lubricant) using as catalyst a mixture of (i) azobisiso-butyronitrile, lauroyl peroxide or benzoyl acetyl peroxide, (ii) benzoyl peroxide, and (iii) tert. butyl peracetate or tert. butyl perbenzoate.

Patent ES-350782-A1 (ES)
Title: Production of hydrogen fluoride from alkali- and alkaline earth fluosilicates
IPC: C01B7/19
Filed: 1968-02-22
Abstract: Hydrogen fluoride is produced by dispersing at least one alkali- and/or alkaline earth-metal fluosilicate in at least one molten alkali- and/or alkaline earth-metal silicate to decompose the fluosilicate into a mixture of solid and gaseous products, and treating this mixture in the presence of the molten silicate at 1300 to 1600 C. with at least 3 moles of water vapour per mole of fluosilicate, the period of treatment and other process conditions being such that substantially complete conversion of the fluosilicate to silicate and hydrogen fluoride occurs. At least one alkali- or alkaline earth-metal fluoride plus silica may be dispersed in molten silicate, in which case the total number of moles of silica plus fluoride is not more than the number of moles of fluosilicate, and in which case at least one extra mole of water is added in said water treatment per mole of fluoride. In Fig. I, fluosilicate ore unloaded at 1 passes via elevator 2, silo 3, bin 4, feed mechanisms 5 and 6, and screen 7 into storage hopper 8, whence an hydraulic ram 10 feeds fines into a first melting zone 34 of reverberatory furnace 11, containing a pool of molten reaction mass 11a. Oversize ore is fed via hopper 14 and feeder 37 into a second melting zone 35, communicating with 34 via holes in barrier 32. The melting zones are charged initially with a silicate melt, which is replenished by the silicate by-product of the process. The fluosilicate reacts in zone 34, and HF, SiF 4 , and other products pass into zone 35a (Fig. 2), and flow as a shallow stream 41 down the incline 29a, whilst being heated by gas burners 38 which produce sufficient water as a combustion product to provide the said 3 moles per mole of fluosilicate, and thus the reaction goes to completion in this zone, so that HF, impurity gases, and dust pass from the furnace to cooler 9, a heat exchanger, and cyclone 12 where dust is removed and recycled to 8. The impure HF passes to absorber 18, where NaF and SiF 4 vapours are removed, then via 19 to heat-exchanger 21, where the HF is cooled to about 100 C., so that it may be readily absorbed in one of the absorbers 20, whilst absorbed HF in the other absorber 20 is desorbed by heating to above 350 C., and recovered as liquid HF, via cooler 22 and refrigerators 23 and 24, in storage tank 26.

Title: Improvements in the control of the refining of pig iron by means of commercially pure oxygen
IPC: C21C5/30
Filed: 1970-01-08
Abstract: In a process for the refining of pig iron by means of commercially pure oxygen the slag layer height in the refining vessel or converter is physically measured by a suitable method. A mathematical expression for the slag height HSC as a function of the oxygen combined with the slag is then established, which expression allows for the fact that the slag height is determined both by physical factors and factors associated with the mean chemical composition of the slag. The expression is then equated with the measured slag height and other quantities in the expression being known the total oxygen combined with the slag is calculated. This calculated quantity is compared with a predetermined set value and a control arrangement (not described) automatically causes the calculated value to approach the set value i.e. by automatic control of the oxygen flow to a lance or of the lance height above the melt or by automatic modification of addition agents. Alternatively the oxygen flow and addition agents may be manually controlled. The slag height may be measured by means of thermocouples mounted along the lance, by radiation responsive cells sensing the radiation from the slag surface, or by sensing the acoustic level of the oxygen jet from the lance the jet noise being attenuated in varying degrees depending upon the height of the slag. The slag height is then obtained by comparing the acoustic noise level with pre-drawn graphs giving the slag height as a function of acoustic level for any lance height.
