The researchers have created new ionic and nonionic chemical surfactants by obtaining nonionic surfactants--mono- and diisopropyl
amine--and then turning them into ionic ones, using poly(methacrylic acid), according to the findings of the study which was recently published in the Journal of Molecular Liquids.
Project Description : To set up a brownfield isopropyl alcohol plant, with high purity diisopropyl
ether (DIPE) as co-product, at Taloja, near Mumbai, with an inside battery limit (ISBL).
ether and cyclohexane were used to observe the activities of enzymes.
1/2]), such as 1 h , Initiators that have been previously evaluated and published include diisopropyl
peroxydicarbonate (ti/2[104[degrees]C] = 20 h), tm-butyl peroxypivalate, tert-amyl peroxypivalate, di-tm-butyl peroxide (DTBP), diakylperoxiydicarbonate, rm-butylperoxidy butyrate, and DEPDC , For this article, the effects of initiator amount, reaction time, mixing rate, and monomer fraction upon molecular weight, polydispersity, and amount of PVDF produced were evaluated using tert-butyl peroxyacetate (TPBA) as an initiator.
Each patient underwent overnight fasting prior to intravenous injection of 5-8 mCi Tc-99m-labeled diisopropyl
The best eluent composition was determined: in first step of development, the mobile phase contained hexane, diisopropyl
ether, and formic acid 90% (6.
The condensation in an alkaline environment, commonly uses alkali including Et3N, triethylene-diamine , dinitrogen complex , tetrabutyl-ammonium hydroxide, piperidine , pyrroline, N,N - diisopropyl
ethyl amine, pyridine, dimethyl-amino-pyridine, aniline, N-methyl aniline, N,N-dimethyl aniline, K2CO3 , zinc (II), and Cd (II) metal-organic frameworks .
Creatinine measurement is based on peroxidase like activity of a copper containing complex that catalyzes the reaction of diisopropyl
benzene dihydroperoxide and 3, 3, 5, 5 tetramethyl benzene.

Several affinity chromatography methods were applied by different workers, including; insolubilized diisopropyl
fluorophosphates (DIP) plasmin as the affinity ligand (18).
Inhibition of the proteinase and esterase activities of trypsin and chymotrypsin by diisopropyl
fluorophosphate; crystallization of inhibited chymotrypsin.
It seems likely that the diisopropyl
radical is the responsible allergenic component (1).
