Abstract: PRODUCING OF PSEUDOIONONES HAVING THE GENERAL FORMULA: CH3-C(CH3)=CR2-A;

CH2=C(CH3)-CHR2-A

AND R3OC(CH3)2-CHR2-A BY REACTION OF DEHYDROLINALOOLS CH3-C(CH3)=CR2-B;

CH=C(CH3)-CHR2-B

AND R3OC(CH3)2-CHR2-B WITH AN ACETOACETIC ESTER CH3-CO-CHR1-COOR3 (WITH A DENOTING -CH2-CH2-C(CH3)=CH-CH=CHR1-CO-CH3; B DENOTING -CH2-CH2-C(CH3)(OH)-C=CH; R1 AND R2 DENOTING H OR CH3; AND R3 DENOTING AN ALKYL GROUP) BY CONTINUOUS REACTION IN AT LEAST TWO VESSELS ARRANGED IN SERIES THE RESIDENCE TIMES IN THE VESSELS BEING ABOUT EQUAL AND THE REACTION TEMPERATURES RISING IN EACH CASE BY FROM 1* TO 50*C. FROM VESSEL TO VESSEL, THE TEMPERATURE IN THE FIRST VESSEL BEING FROM 160* TO 190*C. THE PRODUCTS ARE VALUABLE PERFUMES AND INTERMEDIATES FOR THE SYNTHESIS OF COMPOUNDS OF THE VITAMIN-A AND CAROTENOID SERIES.
