In the crystal structure of the title compound, C(21)H(18)ClFO(3)·0.5C(7)H(8), the toluene solvent mol-ecules occupy special positions on centres of symmetry, and consequently are disordered across this site. The cyclo-hexene ring has a slightly distorted sofa conformation; the two benzene rings are inclined by 72.90 (7)° and their planes make dihedral angles of 30.09 (10) (chloro-phen-yl) and ...

Residents living near a polyurethane foam manufacturing facility expressed concern to health officials over chemical emissions from the plant. Environmental monitoring of ambient air near the plant indicated the presence of toluene diisocyanate (TDI), which was used in foam production. Health officials collected blood samples from 113 residents and analyzed the blood sera for antibodies to TDI ...

Extracellular invertase (EC 3.2.1.26) of Saccharomyces cerevisiae was stabilized against thermal denaturation by intermolecular and intramolecular crosslinking of the surface nucleophilic functional groups with diisocyanate homobifunctional reagents (O==C==N(CH(2))(n)N==C==O) of various lengths (n = 4, 6, 8). Crosslinking with 1,4-diisocyanatobutane (n = 4) proved most effective in enhancing th...

The main objective of this search was to prepare novel soluble polyureas with improved thermal stability. Accordingly, a new types of polyureas was prepared through the polycondensation reaction of a prepared diamine containing ether, keto, and naphthyl groups with 4,4’-diphenylmethan diisocyanate (MDI), toluene-2,4-diisocyanate (TDI), and isophorone diisocyanate (IPDI) in N-methyl-2-pyrrol...

This paper focuses on the Singer-Loomis Type Deployment Inventory (SL-TDI), which is an alternative to the Myers-Briggs Type Indicator (MBTI). The SL-TDI utilizes a continuous, non-forced choice format and therefore is a more accurate representation of Jung's personality theory of psychological types. The purpose of the study reported here is to evaluate the reliability and validity of scores f...
