The theoretical Bravais‚ Friedel‚ Connay and Harker (BFDH) morphological [38] method of MPN crystal with indexed (hkl) planes was determined using the unit cell and positional coordinates of MPN by MERCURY software program [39]. The MPN crystal shows well developed morphology with several habit faces‚ for each face its parallel Friedel plane is also present in the grown crystal which is shown on Figure

Crude Distillation Unit (Unit 1100) The purpose of the Crude Distillation Unit (CDU) is to produce a long residue‚ which is a feedstock of downstream RFCC unit‚ from a mixture of long residue and Oman Export Blend Crude (hereinafter referred to as Mixed Crude). CDU is designed to process 116‚400 BPSD of Mixed Crude‚ consists of 40‚000 BPSD of long residue and 76‚400 BPSD of Oman Export Blend Crude and is supplied from the Mina Al-Fahal refinery. CDU also produces LPG‚ naphtha‚ kerosene and gas

Aldehyde and Ketone 1. ALDEHYDE Definition: An aldehyde is an organic compound containing a formyl group. This functional group‚ with the structure R-CHO‚ consists of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group‚ which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group. Aldehydes differ from ketones in that the carbonyl is placed at the end of a carbon skeleton rather than between two carbon atoms

intermediates - diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl maonic acid. The synthesis of caproic acid involved alkylation‚ saponification‚ and decarboxylation reactions. The first intermediate‚ diethyl n-butylmalonate – a diethyl ester of malonic acid – was synthesized via an alkylation reaction. Alkylation reactions involve the formation and alkylation of an enolate. In this lab‚ NaOEt‚ a strong base was used to pull off one of the most acidic α-hydrogens of the carbonyl ester

Amines are aliphatic and aromatic derivatives of ammonia. Amines‚ like ammonia‚ are weak bases (Kb = 10−4 to 10−6). This basicity is due to the unshared electron pair on the nitrogen atom. Classification and nomenclature of amines Amines are classified as primary‚ secondary‚ or tertiary based upon the number of carbon-containing groups that are attached to the nitrogen atom. Those amine compounds that have only one group attached to the nitrogen atom are primary‚ while those with two or three

It is generally assumed that the toxicity of streptozotocin is dependent upon the DNA alkylating activity of its methylnimethylnitrosourea moiety‚ especially at the O6 position of guanine. The transfer of the methyl group from streptozotocin to the DNA molecule causes damage‚ which along a defined chain of events‚ results in the fragmentation of the DNA. Protein glycosylation may be an additional damaging factor . In the attempt to repair DNA‚ poly(ADP-ribose) polymerase (PARP) is overstimulated
