Abstract: A process is disclosed for preparing a compound of the Formula (I) ##STR1## wherein R.sup.2 is trifluoromethyl or chloro;R.sup.3 is hydrogen or chloro; andX is halogen; wherein a compound of the Formula (II) ##STR2## wherein R.sup.5 is --CFCl.sub.2, --CF.sub.2 Cl, or --CCl.sub.3 ; andR.sup.6 is chloro or trichloromethyl;is fluoroinated either with a mixture of antimony (III) fluoride and antimony (V) chloride or bromide; or with antimony (V) fluoride; or with antimony (V) chloride and hydrogen fluoride.

Abstract: The invention relates to a process for the preparation of DL-.beta.-aryl-amino acids of the general Formula ##STR1## wherein R, R.sub.1 and R.sub.2 stand for hydrogen, halogen, C.sub.1-6 alkyl, C.sub.1-6 alkoxy, nitro or C.sub.1-4 dialkylamino; wherebyin the case of monosubstituted derivatives R and R.sub.1 are hydrogen and R.sub.2 has the same meaning as stated above and can be attached to position 2, 3 or 4 related to the methylene group;in the case of disubstituted derivatives R is hydrogen and R.sub.1 and R.sub.2 have the same meaning as stated above and are attached to positions 2,3; 2,4; 2,5; 2,6; 3,4 or 3,5 related to the methylene group;in the case of trisubstituted derivatives R, R.sub.1 and R.sub.2 have the same meaning as stated above and are attached to positions 2,3,4; 2,3,5; 2,3,6; 3,4,5 or 3,4,6 related to the methylene group.

Abstract: A chlorinated quinoline derivative of formula (I) ##STR1## wherein R.sup.1 is --CCl.sub.3, --CF.sub.3, --CHCl.sub.2 or --CH.sub.2 Cl, R.sup.2 is hydrogen when R.sup.3 is not hydrogen, or is halogen, C.sub.1-4 alkoxy, C.sub.1-4 alkyl or R.sup.1, R.sup.3 is hydrogen when R.sup.2 is not hydrogen or is halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy or CF.sub.3, R.sup.6 is hydrogen or halogen, X is halogen. The compounds are made by chlorination of selected compounds as disclosed and the new compounds can have antimicrobial, antifungal or analgesic effects.

Abstract: N-phosphonomethylglycine is prepared from glycine and parsformaldehyde to obtain an intermediate which is reacted with dialkylphosphite to obtain an ester of the desired compound which is then hydrolyzed.

Abstract: Transport processes such as emulsification, mass transfer, dissolution, washing or chemical reaction are carried out by admixing two substantially immiscible fluid phases with a rotary agitator having thereon filamentary elements that occupy 0.1% to 20% of the space to be swept thereby, whose thickness is 10-5000 .mu.m and whose thickness-to-length ratio is 1:5 to 1:5000, there being several thousand such elements on the rotor, that rotates at several thousand rpm, the elements having peripheral speed of at least 30 m/s.-- The operation is improved by also including in the fluid medium solid particles of a size 1-1000 .mu.m.
