4%, wt/wt) obtained from the extract in the current study indicates its suitability for the resinification
This diversity of fresh resources, joined with the novel approaches and contemporary purifying procedures, make it possible to eradicate the difficulties of ancient technology for vegetable oils, such as resinification
, the viscosity increased and the development of acidity.
At this stage, by restricting the addition of the long-chain and short-chain components to a limited amount, resinification
is kept in an incomplete state, and the product (cellulose bonded with cardanol and acetic acid) is efficiently recovered through precipitation separation (+filtration under reduced pressure).
Optimization of four resinification process parameters (resinification time, resinification temperature, NaOH/liquefied wood molar ratio and methanal/liquefied wood molar ratio) was carried out by using orthogonal experiment design.
As showed in table 1, four resinification factors, including resinification time, resinification temperature, molar ratio (NaOH/liquefied wood) and molar ratio (methanal/ liquefied wood), were selected to be optimized by using the L16 (45) orthogonal table in term of the viscosity, solid content and pH of resinification product.
All of resinification factors investigated have effect on the viscosity and solid content.
However, for local-born members of the second and third generations, already imbued with American ideals and sentiments, resinification
was often a difficult matter of adjustment and redefinition, as reflected by their different constructions of such American labels as "Chinese American" and "Asian American," implying dual identifications.
Effective antioxidants usually inhibit resinification
for several hours at 130[degrees]C, the time depending on the effectiveness of the inhibitor.
Grinding too small can rupture surface oil glands causing evaporation of essential oils and loss of aroma by oxidation and resinification
Liquefaction of wood in phenol and the resinification
of the phenolated wood.
After 1945 the opening of job opportunities outside of Chinatown made these schools and their instruction seem, for a time, to be unnecessary More recently, as prospects for trade with China have developed and as an interest in resinification has appeared in some North American Chinese communities, new cultural centers and other organizations have sponsored language and cultural instruction either in Cantonese or in Mandarin (Wickberg, 1988).
Instead, the striking things (to me, at least) about resinification in Hawai'i are how early it began to be of concern and how little it seems to have been influenced by community replenishment (which has been rather slight).
