The purpose of this study was to investigate the effect of type of alcohols and humectants in inks formulation, and the papers surface morphology on the ink-jet printing properties. In order to investigate the influence of alcohol and humectant types on printing properties, the optimum ink formulation from previous study, which contained C.I. Reactive Blue 21 Ink2 was formulated with different ...

Self-association of alcohols; including ethanol, methanol, cyclopentanol and octanol in separate mixtures with inert solvents have been studied using FT-IR spectroscopy. Except for the band at 3640 cm–1 in the IR spectrum of the alcohols which is due to the monomer species, the presence of other bands in the region of stretching vibrational frequencies of OH (3100-3700 cm–1) are attributed to t...

Allitol, D-talitol and L-iditol are sugar alcohols that are rare in nature. Due to their previous rarity, little is known about the laxative effects of these rare sugar alcohols. Therefore, reliable data on the laxative effect that these sugar alcohols cause in experimental animals could help to evaluate the effectiveness of new monosaccharide laxative drugs. To investigate the laxative effect ...

The enantioselective addition of alcohols to imine electrophiles has been shown to proceed in the presence of a catalytic amount of a chiral phosphoric acid catalyst. The reaction allows for the formation of the respective chiral N,O-aminals in excellent yield and enantioselectivity. A total of 11 different alcohols and 11 different imines were successfully used as a clear demonstration of the ...

Methoxymethylation of a variety of alcohols was performed using formaldehyde dimethyl acetal in the presence of 1,3-dichloro-5,5-dimethyl hydantoin [DCDMH] and Poly N,N′-dibromo-N-ethyl naphthyl-2,7-disulfonamide [PBNS] as catalysts at room temperature and under solvent-free conditions. Our experiments show that primary and secondary alcohols can be smoothly converted into the corresponding MOM...

In Ziegler-Natta olefin polymerization, the pore architecture of catalysts plays a crucial role in catalytic performances and polymer properties. While the type of preparation routes (such as chemical reaction and solution precipitation) greatly affects the catalyst pore architecture as a result of different solidification mechanisms, the modification of the pore architecture within a given rou...

Anionic polyurethane dispersants APUDs were used as dispersing agents in formulation of waterborne paints. The APUDs were synthesized by three steps. In the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diisocyanate IPDI, dimethylol propionic acid DMPA in presence of acetone as solvent and dibutyltin dilaurate DBTDL as catalyst. Then, carboxylic polyure...

An extensive study of Higher Alcohols Synthesis (HAS) from syngas using alkalized MoS2 catalysts supported on Carbon Nanotubes (CNTs) is reported. Up to 30wt.% of Mo and 8wt.% K are added to the CNTs by impregnation method. The catalysts were characterized by different methods and the performance of the catalysts was assessed in a micro-reactor. TEM images showed that mo...

This case report describes a patient who developed allergic contact dermatitis to chlorhexidine skin preparation applied for transversus abdominis plane block, but not different solution the surgical field. The had presented an elective inguinal hernia repair. He known history of anaphylaxis non-steroidal anti-inflammatory medication was otherwise well. surgery completed uneventfully. Three or ...
