Investigations on Gas Phase and Wet
Xanthation
Better knowledge of how the interrelations between different xanthation parameters influence filterability is essential for process optimization.
Erich Treiber, Lars Wangberg, SVENSKA TRAFORSKNINGSINSTITUTET STOCKHOLM.,
1968

Polymeric Materials Encyclopedia, Twelve Volume Set
Time of Xanthation An increase in time of xanthation increases the number of the
xanthate groups, indicated by the iodine value ("y number) Figure 3. To trace the
influence of the degree of xanthate substitution (i.e., -y number on the degree of ...

Regenerated Cellulose Fibres
During xanthation, the mercerised alkcell reacts with CS2 vapour to produce
sodium cellulose xanthate. It is this derivative which is soluble in dilute caustic
soda, and when so dissolved forms viscose dope. The reaction is performed
under ...

Wood: chemistry, ultrastructure, reactions
Several studies are concerned with optimizing xanthation and the properties of
the resulting xanthate by a slight hydroxyalkylation of the alkali cellulose (
Lukanoff, Philipp 1967; Ioleva, Papkov 1968; Jasunskaja, Konovalova 1968).
Though ...
Dietrich Fengel, Gerd Wegener,
1983
Unlike many other esterification reactions on cellulose fiber substrates, such as
the nitration or the acetylation, in the xanthation trisubstitution does not occur
readily. In commercial xanthation of alkali cellulose with carbon disul- fide in the ...

Handbook of Fiber Chemistry, Second Edition, Revised and ...
RCel,0- + CS2 — RCcllOCS2- (6) Xanthation is an equilibrium reaction, and as
the CS2 is used to form byproducts, it is replaced by decomposition of the
xanthate. There is an induction period in the formation of trithiocarbonate. At
elevated ...

Issues in Land and Water Engineering: 2013 Edition
According to news reporting originating in Edmonton, Canada, by VerticalNews
journalists, research stated, “A xanthation-modified polyacrylamide (PAM),
named PAM-X, was synthesized. In single mineral flotation tests.” The news
reporters ...

Manufactured Fibre Technology
fluffy crumbs is sufficient and exposure to outside air is avoided as otherwise the
crumbs dry out and carbon dioxide from air produces carbonates which affect
xanthation and filterability. Ageing is carried out for 1-3 days at a temperature of ...

Tappi: Technical section
in AC, 80% CS2 (on cellulose), 32°C xanthation temperature, initial pressure (
before addition of CS2) pa = 335 mm Hg. In agreement with generally known
facts and previous work (2), the 7-number increases with increased xanthation
time.

Concise Polymeric Materials Encyclopedia
In this work, we considered different variables of the grafting reaction that uses
the ionic xanthate method, such as the temperature of the grafting reaction, the
degree of xanthation (through variation of time of xanthation and the
concentration ...
